Abstract:

The purpose of this exploratory research was to investigate potential factors (i.e. gender, time lapse between the latest statistics class and completion of the statistics test, grade point average (GPA), attitude towards statistics), which are associated with the comprehension and retention of statistical knowledge in Baccalaureate Psychology students. The criterion variable was statistical competency, which was measured in five subdomains: basic concepts, descriptives, correlation/regression, hypothesis testing, and inferential statistics.

Abstract:

<p> The purpose of this quantitative, survey-based study was to investigate the relationship between anger and hatred in an effort to learn more about how to understand and curb the problem of workplace violence. In particular, perfectionism was examined as a possible mediator of the relationship between anger and hatred. The study was conducted on a sample of 1,192 people. The statistical techniques of correlation, partial correlation, linear regression, and principal components analysis (PCA) were used to examine the relationship between variables in the study. The following conclusions were

While a variety of researchers have identified periodic recurrences in infant behavioral state with various time-series techniques, the appropriateness of techniques which identify periodic recurrences in all infants at all ages have been questioned. The purpose of this study was to compare the utility of four time-series techniques used in the analysis of periodic recurrences in the behavioral state of 21 newborns during a 2 hour observation period. For quiet sleep, active sleep and awake states the period length of the major rhythm was estimated by 1) binary spectrum analysis, 2) binary auto

Abstract:

Within the past few decades, methodologists have made major advances in statistical methods for the analysis of change using longitudinal panel data, particularly in the area of modeling individual differences (Bryk & Raudenbush, 1987; Collins & Horn, 1991; Rogosa, 1991; Willett & Sayer, 1994; Willett, Singer, & Martin, 1998). These advances have made it possible for researchers to measure change and the correlates of change in ways that were not thought possible a few decades ago. These improvements should allow researchers to make stronger and more informed inferences regarding change over t

The belief that certain disorders will produce specific patterns of cognitive strengths and weaknesses on psychological testing is pervasive and entrenched in the area of clinical neuropsychology, both with respect to expectations regarding the behaviour of individuals and clinical groups.

To the contrary, studies examining patterns of cognitive performance in different clinical samples without exception find more than one pattern of test scores.

The shortcomings of the proportion above cut (PAC) statistic used so prominently in the educational landscape renders it a very problematic measure for making correct inferences with student test data.

A better alternative is using mean-based statistics that can translate to parametric effect-size measures. However, these statistics as well can be problematic. When Gaussian assumptions are

The main research question in this thesis explores why some people volunteer and give money compared to those that do not. The thesis builds on existing research that explains volunteering and giving, but is primarily concerned with showing how the social environment – or the context – in which people live can explain individual decisions to volunteer and give. This thesis answers three main research questions with this central theme in mind. First, how do the background characteristics of people explain whether they volunteer or give?

In longitudinal settings, modeling the covariance structure of repeated measure data is essential for proper analysis. The first paper in this three-paper dissertation presents a survey of four journals in the fields of Education and Psychology to identify the most commonly used methods for analyzing longitudinal data. It provides literature reviews and statistical details for each identified method. This paper also offers a summary table giving the benefits and drawbacks of all the surveyed methods in order to help researchers choose the optimal model according to the structure of their data.

Latent variable models play an important role in psychological and educational measurement, which attempt to uncover the underlying structure of responses to test items. This thesis focuses on the development of statistical learning methods based on latent variable models, with applications to psychological and educational assessments. In that connection, the following problems are considered. The first problem arises from a key assumption in latent variable modeling, namely the local independence assumption, which states that given an individual's latent variable (vector), his/her respo

Abstract:

中介效應和調節效應分析在心理學研究中廣泛存在。調節效應發生時，自變量和因變量的關係的強度或方向會因調節變量的水平而有所改變。另一方面，中介效應發生時，自變量會通過中介變量對因變量來產生影響(Baron& Kenny,1986) 。心理學家經常結合這兩種效應以處理更複雜的問題，例如:調節作用是如何發生或中介作用在什麼情況會有所改變。研究學者定義前者為有中介的調節作用，後者為有調節的中介作用。儘管在文獻中有許多關於中介的調節效應和有調節的中介效應的分析方法的討論，對於理解這兩種效應的混亂仍然存在。此外，結構方程模型分析方法雖然比傳統的迴歸分析方法更靈活和有效地處理這兩種效應的分析，但是文獻上卻甚少討論如何應用結構方程模型於有中介的調節作用和有調節的中介作用的分析上。本論文回應以上提出的問題，主要討論如何把結構方程模型的分析方法應用在有中介的調節效應和有調節的中介效應的分析上，論文的第一部份會透過闡明五種常見有關於有中介的調節效應和有調節的中介效應的概念模型以消除研究橕者對這兩種效應定義的誤解。在論文的第二部分將會提出一個用以轉換有中介的調節效應和有調節的中分效應的概念模型為能應用於結構方程模型分析法上的模型的統一方法，讓研究學者能統一方法中提出的規則簡易地把假設模型變成為可為結構方程模型作分析的模型。模擬實驗來比較迴歸方法和結構方程模型方法的實際效用。結果顯示，這兩種分析方法發現相近。

Multiple imputation is a state-of-the-art missing data method recommended by methodologists. Multiple imputation methods can generally be divided into two broad categories: joint model (JM) imputation and fully conditional specification (FCS) imputation. JM draws missing values simultaneously for all incomplete variables using a multivariate distribution (e.g., multivariate normal).

Data are collected on the variables and a covariance or correlation matrix is computed. The covariance structure modeling (CSM) procedure estimates the parameter values in the model that has been specified and assesses how well the model fits the data. Models failing to provide a good fit to the data are often modified. This process is known as a spe
