Abstract:

Subjects sorted decks of cards depicting pie charts and divided bar graphs on two criteria: the proportion shown in the graph, and the graph's overall size, or scaling. Sorting times and errors were measured. For divided bars, performance was impaired when subjects were required to sort the proportion and the overall scaling varied. No such impairment occurred for pie charts. The results suggest that proportion and scaling are integral dimensions for divided bar graphs, but separable dimensions for pie charts. Subjects can judge angles or slopes with pie charts having different scaling, but must estimate a ratio prior to classification with different-scale divided bars. In sum, showing proportions with divided bar graphs can be problematic if the scaling of the graph varies, but pie charts are not similarly affected.

Abstract:

The vast majority of graphs appearing in the psychiatric literature consist of the traditional line graphs, histograms, and bar charts. Over the past decade, new graphing techniques have appeared which make the data easier to read and which present much more information than simply group means and confidence intervals. These methods include horizontal bar charts, dot charts, stem-and-leaf plots, box plots, and notched box plots. This paper describes these new techniques, as well as older ones, such as smoothing, and warns against using some of the options found in graphics programs: 3-dimensional (3-D) graphs, stacked graphs, and pie charts.

Abstract:

Subjects judged change and proportion when viewing graphs in two experiments. Change was judged more quickly and accurately with line and bar graphs than with pie charts or tiered bar graphs, and this difference was larger when the rate of change was smaller. Without a graduated scale, proportion was judged more quickly and accurately with pie charts and divided bar graphs than with line or bar graphs. Perception is direct when it requires simpler or fewer mental operations; we propose that perception of change is direct with line and bar graphs, whereas perception of proportion is direct with pie charts and divided bar graphs. The results are also consistent with the proximity compatibility principle. Suggestions for improving the design of graphical displays are given.

Abstract:

Previous research is equivocal on the most efficient, effective methods for displaying quantitative information in tables and graphs. Guidelines suggest different display types are more appropriate for certain purposes but not others. However, there is little empirical evidence to support the recommendations. This study examines several methods of displaying quantitative information (e.g., line graphs, bar charts, tables) factorially crossed with different kinds of data extraction questions (i.e., inquiries about trends, comparisons, and exact numerical quantities). Results showed that tables, bar grables (combined bar graph and table) and line grables produced the most accurate responses, and line graphs and bar charts produced the fastest responses across question types. Results are discussed with respect to prior theoretical work and the potential benefits of hybrid forms of quantitative data displays for multiple kinds of data extraction inquiries.

Abstract:

This study investigated the graphing skills and some affective states of middle school students about graphs by their gender, grade level, and the common graph types used in science courses. Participants’ line graph skills, self-efficacy beliefs and attitudes toward graphs, and their personal literacy perceptions about different graph types (line, bar, and pie) are explored quantitatively. Qualitative data was collected about the views of participants about graphs in general, as well as about the factors that impact students like/dislike certain graph types. Based on the findings, while participants were found to lack line graph skills, they were found to hold high self-efficacy beliefs and positive attitudes toward graphs. No significant difference among the dependent variables was found based on gender; however, grade level and graph type variables were found to impact students’ graph skills and personal graph literacy perceptions. Among the commonly used graphs in middle schools, a vast majority of students favored bar graphs, mostly due to the simplicity of them, and disliked pie charts, as finding them difficult to draw.

Abstract:

One topic area where technology can have an immediate impact in the mathematics classroom is graphing. Because of a variety of readily available software packages, graphs have become a universal method of representing mathematical relationships. From the charts in USA Today to the many diagrams of Ross Perot, the general public sees more graphs than ever before, and they need to have a better understanding of what graphs really represent. In the past, a graph could only be created by hand; therefore, most curricula emphasized the actual graphing of equations. With the help of technology, teachers can now concentrate on teaching students how to investigate what the graphs represent as well as how to interpret the graphs.

Abstract:

Time-weighted graphs are used to detect small shifts in statistical process control. The aim of this study is to evaluate the inclination of the acetabular component with CUmulative SUM (CUSUM) chart, Moving Average (MA) chart, and Exponentially Weighted Moving Average (EWMA) chart. The data were obtained directly from thirty patients who had undergone total hip replacement surgery at Ondokuz Mayis University, Faculty of Medicine. The inclination of the acetabular component of these people, after total hip replacement, was evaluated. CUSUM chart, Moving Average chart, and Exponentially Weighted Moving Average were used to evaluate the quality control process of acetabular component inclination. MINITAB Statistical Software 15.0 was used to generate these control charts. The assessment done with time-weighted charts revealed that the acetabular inclination angles were settled within control limits and the process was under control. It was determined that the change within the control limits had a random pattern. As a result of this study it has been obtained that time-weighted quality control charts which are used mostly in the field of industry can also be used in the field of medicine. It has provided us with a faster visual decision.

Abstract:

This survey design study was designed to test whether the graph skills and affective states of middle school students about graphs differ by their gender, grade level, and graph types (line, bar, and pie). The data collection instruments consisted of two scales developed by the authors and a Graph Skills Test, which consisted of graph questions from the previous TIMSS and PISA exams. Based on the findings, while middle school students were found to succeed at reading the data level graph questions, they were found to struggle in questions requiring higher graph skills, such as graph interpretation and graph construction. As for the affective states investigated, participants were found to hold high self-efficacy beliefs and positive attitudes toward graphs. No significant difference among the dependent variables (graph skills, self-efficacy beliefs about graphs, attitudes toward graphs, and graph literacy perceptions) was found by gender; however, grade level and graph type variables were found to impact students’ graph skills, graph attitudes, and personal graph literacy perceptions. Middle school students with less school experience with graphs (seventh graders) were found to hold more positive attitudes toward graphs than the eighth graders. On the contrary, eighth graders were found to perform better at graph questions requiring interpretations of the graph data. Also, participants in all subgroups were found to hold significantly higher personal graph literacy perceptions for the bar graphs, than the line graphs and pie charts. Based on the findings of the study, while middle school students were found to hold positive affective states about graphs, they were found to lack advanced graph skills. In agreement with the previous literature, it is recommended that graph literacy should become a dedicated part of the school curriculum.

Abstract:

This paper presents graphs which simplify the task of selecting bivariate anthropometric dimensional combinations which are to be representative of the design population. Data for the graphs are based on defining bivariate percentile pairs in a manner modeled after the techniques of defining univariate percentiles. The charts are presented in “Z” format and assume that the bivariate data are normally distributed. The charts and the method of defining bivariate percentile combinations should be of use in many areas of anthropometric design and evaluation including defining representative computer implemented manikins.

Abstract:

Evaluations for jurisdictions with Weed and Seed and similar community policing initiatives can sometimes fail to tell the full story because of the complexity of the issues involved. Complete evaluations require many complex graphs and charts that could overwhelm all but the most interested reader. Crime mapping, using the same data used for the extensive display graphs and charts, has proven to be an effective way to present large volumes of complex information. This article describes the Wilmington Crime Index, a unique mapping method that takes into account year-to-year changes in both reported crimes and arrests.

Abstract:

Purpose: To illustrate the use of one particular graphical method, the event chart (Lee et al., 2000), for the display of adverse events (AE’s), along with other important considerations such as time on treatment/intervention, severity of AE’s, treatment assignment, gender, etc., in longitudinal studies. These graphs can also include other key information such as efficacy measures and time-dependent covariates of interest. Methods: Emphasizing an application of a dose-ranging smoking cessation trial of naltrexone, we use event charts to convey a few potentially interesting findings from the complex data from this trial, with particular attention paid to the analysis of the safety (AE) data from the subset of individuals who dropped out before the end of the treatment phase of the study Results: The event charts conveyed some interesting findings regarding relationships between gender, AE’s and dropout time, as well as between treatment group, AE’s and dropout time, and between AE burden and dropout time. Conclusion: Event charts can be one of the helpful exploratory tools in investigating the pattern of adverse events and their possible association with covariates and time on treatment/intervention in longitudinal studies. Findings from the event chart analysis of AE’s could potentially lead to more formal statistical analysis and modeling. Software for generating these event charts is available in R and S-Plus.

Abstract:

We identified the graphical perceptual information needs of older adults (≥ 60 years of age) through a set of psychophysical experiments on bar, stacked, and pie charts. The results are compared with those of a general population (< 60 years of age). We conducted the experiments as online remote studies with 202 total participants across two experimental types: (1) comparison judgments of graphs (50 older adults, 50 general population) and (2) proportion judgments of graphs (52 older adults, 50 general population). Older adults took longer than the general population to complete tasks across both comparison (4.09 s) and proportion judgments (3.66 s). However, this translated to an approximately equal level of perceptual accuracy. Bar charts were the most effective graphical display when considering both speed and accuracy. Older adults were more accurate using pie charts compared with the general population in the comparison task.

Abstract:

In this paper, we study the foreign exchange rates of a pair Russian ruble/US dollar on the subject of fractality. It has been shown that the time series studied quotes has the basic fractal properties. With the help of the Hurst exponent was calculated by the Hausdorff dimension, which was a fractional number that supports the hypothesis of fractality. Volatility charts were compared with charts of known solutions of the fractional differential equation wandering point particle in a self-similar fractal set. The solution of this equation is a function of Mittag-Leffler. It is shown that graphs of the Mittag-Leffler function repeat exactly the structure of graphs volatilities for different periods of time. The solution of such an equation is written out using the Mittag-Leffler functions. The graphs of these decisions are compared with the volatility charts for different time periods. It also clearly confirms that the Russian currency market is a fractal. Thus, these results will help in predicting market behavior in advance a preset time in the future, which is almost a valuable tool for working with Russian currency market.

Abstract:

It has been approximately 100 years since the very first formal experimental evaluations of statistical charts were conducted. In that time, technological changes have impacted both our charts and our testing methods, resulting in a dizzying array of charts, many different taxonomies to classify graphics, and several different philosophical approaches to testing the efficacy of charts and graphs experimentally. Once rare, charts and graphical displays are now everywhere—but do they help us understand? In this article we review the history of graphical testing across disciplines, discuss different direct approaches to testing graphics, and contrast direct tests with visual inference, which requires that the viewer determine both the question and the answer. Examining the past 100 years of graphical testing, we summarize best practices for creating effective graphics and discuss what the future holds for graphics and empirical testing of interactive statistical visualizations.

Abstract:

Abstract. INTRODUCTIONBy far the most widely available computer programs for recording, manipulating, and displaying numerical data are spreadsheets, such as Microsoft Excel™ and Lotus 1-2-3™. These are powerful and flexible tools and for most workers this is an obvious way of recording micropalaeontological data. However, they have been primarily produced for business users and have limited abilities when it comes to plotting scientific graphs. This note describes some indirect but rapid methods, for using the standard graphing tools in such packages, to produce additional types of graphs of value to micropalaeontologists.STACKED HISTOGRAM CHARTSFigure 1 is a stacked histogram chart, produced in Microsoft Excel™. This type of diagram is useful, for instance, in displaying variations in size of a species between samples through a section. Stacked histogram charts are not directly supported by any spreadsheets that I have seen. As a result, they can usually only be produced by rather inefficient techniques. For example, making a separate chart for each sample and then combining them in a graphics program. The indirect approach used here is to separate each true data series with a mirror image padding data series, which is not displayed. The entire diagram is then plotted as a single chart. The steps for doing this are:(1) Enter the data (specimens per size class) in a spreadsheet (samples v. size classes).(2) Between each pair of data columns insert a column with equations which will calculate mirror image padding data. These will have the form C3 = . . .

Abstract:

In this article we present the Network Analysis Profiler (NAP v2.0), a web tool to directly compare the topological features of multiple networks simultaneously. NAP is written in R and Shiny and currently offers both 2D and 3D network visualisation, as well as simultaneous visual comparisons of node- and edge-based topological features as bar charts or scatterplot matrix. NAP is fully interactive, and users can easily export and visualise the intersection between any pair of networks using Venn diagrams or a 2D and a 3D multi-layer graph-based visualisation. NAP supports weighted, unweighted, directed, undirected and bipartite graphs.

Abstract:

The topography directly influences the functioning of an irrigation system, being necessary the determination of the uniformity to verify its performance. Statistical quality control is a powerful tool for verifying the quality of a process. Thus, it was aimed to use the statistical control of quality in the evaluation of the uniformity of a drip irrigation system in different slopes. The Christiansen’s uniformity coefficient (UC) and Uniformity of Distribution (UD) were determined and analyzed by the control graphs of Shewhart, Zones and CUSUM and by the indices of process capacity (Cp, Cpl and Cpk), in different slopes (0%, 2% and -2%). The slope irrigation was more uniform (UC = 99.03% and UD = 98.45%), however, for all the graphs studied it was out of statistical control. Zone charts were more sensitive than the CUSUM and Shewhart charts.

Abstract:

The present paper reviews a classic work of scholarship on Russian verse, Kiril Taranovsky’s Russian Binary Meters. The analysis demonstrates that the two sections of the book are tacitly at odds with each other, and that the more famous second part (on “regressive accentual dissimilation,” and more generally the evolution of rhythmic patterning in various meters) does not fully take into account the observations of the first part (on accentuation in Russian verse). In particular, two elements are missing from the second part: the role of hypermetrical stress and the relative strength of stresses on strong syllables. Taranovsky recognized these phenomena, but they are nowhere reflected in his statistical data and conclusions, presumably because to take them into account would require an element of subjectivity. Taranovsky and his followers were proud that they could produce verifiable (repeatable) results. However, these results can only be repeated by scholars who agree on the same strict set of rhythmic conventions. The author of this essay argues that these conventions are oversimplifications. By omitting the question of hypermetrical stress, Taranovsky ignores some of the most important and memorable lines of Russian poetry. And by disregarding the question of relative stress, he creates an “acoustical” model of poetry that in no way corresponds to how it is actually recited. The paper ultimately suggests that scholars of verse should be more concerned with poetry as performance and less with the attempts to turn verse rhythm into an exact science.

Abstract:

Recent advances in graphing software and output devices have given new tools to graphic artists and have enabled writers and technicians to compose graphs that rival those of professional artists. The products of both professionals and novices suggest, however, that the users of such software either intend to distort data and manipulate their readers or that they do so out of ignorance. This article describes and illustrates seven types of distortion in graphs, explains the mechanisms of distortion, and recommends methods for the avoidance of distortion. The seven types include manipulations of scale ratios, of the second dimension, of the third dimension, of color, of composition, of symbolism, and of affect.

Abstract:

To solve the problems such as too much trial-and-error, limited material being involved in the graphs and calculation results being obviously influenced by artificial factors and errors of the graphs in the design of external pressure vessel according to current standard ASME Ⅷ-1, GB150 and EN13445, the mathematic expression of the graphic charts is examined, and a set of analytical equations and algorithms for the linear and nonlinear instability of external pressure vessel are established. The equation was applied to calculate the ultimate buckling pressure of cylinder and spherical shells. The algorithm here provided can not only avoid the shortages of current graphic analysis methods, but also be convenient for technicians to calculate, which could enrich and consummate the graphic charts in the current standards and be useful to the design of external pressure vessels to be made of new materials.

Abstract:

The accuracy of predictions of future student performance on the basis of graphing data on semi-logarithmic charts and equal interval graphs was examined. Predictions made for 83 students on the basis of reading and written expression data collected over 7 weeks were compared to actual data collected for weeks 8, 9, and 10. Analyses of deviations between predictions and actual scores indicated that predictions were more accurate when the data had been graphed on equal interval graphs. Implications for training are discussed.

Abstract:

Abstract The choice of an optimal solution among various available technological and material undertakings often becomes a problem of the engineering community. A multi-criteria technical and economic analysis is used in order to facilitate decision making. The objective of this article is to present biplot methods and radar charts as a possibility of graphic presentation of research results by obtaining an optimal solution on the example of an analysis of technological and material undertakings of acoustic screens. The research consisted in identifying technological and material solutions of the selected acoustic screens, and then defining features (criteria) and cases (technological and material solutions). The results were presented in radar charts and biplot-type graphs. The methodology consisted in generating a data matrix, which is then processed, decomposed and finally scaled. The calculations were carried out in the Statistica programme. The carried-out analysis showed that the spider web and biplot methods differ from each other. The biplot graph more precisely describes the solutions, and it presents the correlations between variables and cases.

Abstract:

Abstract: The purpose of this study was to examine the forms of representation constructed by primary school students in solving mathematical problems. Representation is the basis or foundation of how a student could understand and use mathematical ideas. The forms of representation, such as charts, graphs, and symbols, are essentially a long process of learning mathematics, but unfortunately these representations are often thought of and studied in its final form. Actually, representations should be given as support in the process of understanding concepts, the associations of mathematics, mathematical communication, constructing arguments, and apply mathematical concepts in everyday life through modeling. This research showed that the forms of representation constructed by the students are extremely varied. They are constructed in tables, images, patterns, and in the formal forms of mathematics (the formula). This study was also revealed that some students are able to develop forms of representation using logical mathematical processes. Students begin to formulate a representation using known premise, set the table, make conjecture, and subsequently arrange a formal representation.Keywords: mathematic representation, tables, charts, graphs, statements.

Abstract:

Perhaps one of the strongest connections between the national standards in mathematics and science education is their shared emphasis in all these areas: students collecting, organizing, and describing data; constructing appropriate charts and graphs to summarize the data; making predictions based on the data; and testing these predictions and conclusions (NCTM 1989, 2000; NRC 1996).

Abstract:

With the vocabularies of their own disciplines, students majoring in technical subjects can access fresh insights into how writers write. For example, the symbols of computer flowcharts may bring insights when used to monitor rhetoric. Charts of organizational hierarchies, such as those that many corporate executives use, may illuminate equally well the shifting hierarchies of the characters in a work of fiction. Graphs and charts of syntactic and lexical networks may reveal the hidden structures of a narrative. An engineering major needs to see how a writer engineers words, a business major to see how a writer establishes hierarchies, a computer science major to see how a writer devises the flow of rhetoric. If we encourage students to explain literature with the professional vocabularies of their own disciplines, we can train them as lively apprentices, not as drudges. If we English teachers heed our students' special vocabularies, we may expect students to examine our own jargon more thoughtfully, such as the vocabulary by which we chart subordination and punctuation. Literature is everyone's heritage. No discipline monopolizes the critical insight or the vocabulary with which to articulate it.
