Abstract:

This study aims to describe the effects of variability through data simulation to determine which aspect of variability that maximizes coefficient of Cronbach Alpha reliability. Cronbach Alpha is widely used for estimation of reliability, in recent still. This study served a conceptual and practical simulation for estimating the profound aspect of Cronbach Alpha coefficient relating to the variability of the data. This study carried out with data simulated using the rand between method by Microsoft Excel then simulate different categorical data responses to different range of items by manipula

Abstract:

<p>This research aims to compare the internal consistency of reliability coefficient on classical test theory. Estimation accuracy of internal consistency reliability coefficient used several methods of the coefficient reliability formulation. The methods are Split-Half Method, Cronbach Alpha formula, and Kuder Richardson formula. Determination of the test reliability coefficients used also some formula and then their results were compared with the results of their estimation accuracy. This research is a quantitative descriptive. Data were analyzed based on responses of national chemistr

Abstract:

De nombreux chercheurs en psychométrie soutiennent que le coefficient alpha de Cronbach (1951) n’est pas une mesure adéquate de la fidélité (reliability) d’un test. C’est dans l’optique d’améliorer les pratiques d’analyse de données que ce court article va présenter les fondements théoriques de la fidélité, synthétiser les principales limites de l’alpha en plus de présenter de façon concise deux alternatives très prometteuses: le great lower bound et l’omega. Des logiciels gratuits et en téléchargement libre sont mentionnés pour obtenir un estimé de ces coefficients.

Abstract:

Cronbach alpha and Cohen kappa were compared and found to differ along two major facets. A fourfold classification system based on these facets clarifies the double contrast and produces a common metric allowing direct comparability. A new estimator, coefficient beta, is introduced in the process and is presented as a complement to coefficient alpha in estimating the psychometric properties of test scores and ratings.

Abstract:

Object This study was undertaken to assess the reliability of observations of postoperative photographs in assigning House-Brackmann scores as outcome measures for patients following resection of vestibular schwannomas. Methods Forty pictures of differing facial expressions typically elicited from patients for assigning House-Brackmann scores were individually evaluated by neurosurgery residents and faculty members at the University of Alabama at Birmingham; a score was assigned to each picture by the individual raters. The interrater reliability was measured using the Spearman correlation coe

Abstract:

Zimet's knowledge of AIDS scale was completed anonymously by 2,209 university students to assess whether a split-half approach in which items in each half were matched for content would provide better estimates of reliability than other methods. Analysis indicated that the odd-even Spearman-Brown split-half reliability coefficient was lower than both the alpha coefficient and the content-based split-half coefficient. The Cronbach alpha was similar to the content-based Spearman-Brown reliability coefficient.

Abstract:

Objective: Internal consistency of scales is crucial for the quality of clinical practices, and scales that measure various aspects of clinical disorders must possess acceptable internal consistency. In the assessment of the internal consistency of the scales, the present study considered the Cronbachs alphas coefficient. This study aims (1) to provide a practical sample size guide based on Cronbachs alpha for medical researchers; (2) to investigate the factors related to the determination of the sample size needed for a correct estimation of Cronbachs alpha. Method: The calculation steps

Abstract:

This study aimed to develop a scale to determine the democratic behavior levels of children in early childhood. The study group included a total of 486 children attending kindergartens and primary school nursery classes in Melikgazi, Kayseri. Scale reliability was tested by using intra-group correlation values, item analysis coefficients, Cronbach’s Alpha reliability coefficient (0,98), and the Hotelling T2 test result [ 830,12 and (p<0.001)]. For validity testing purposes, the Cronbach Alpha coefficient, KMO test result (0,97), the Bartlett test and item analysis (p<0.001) were calculat
