Cronbach Alpha can be used for both binary-type and large-scale data. On the other hand, KR can be applied to dichotomously scored data only. 2. Spilt-half can be viewed as a one-test equivalent to alternate form and test-retest, which use two tests. In spilt- half, you treat one...
Cronbach’s alpha tests to see if multiple-questionLikert scalesurveys are reliable. These questions measurelatent variables—hidden or unobservable variables like: a person’s conscientiousness, neurosis or openness. These are very difficult to measure in real life. Cronbach’s alpha will tell you ...
I have a correlation matrix, how can I calculate Cronbach's alpha of my factors using SAS? I don't have the original data set, just the correlation matrix, N, mean and std. I have a correlation matrix like this: DATA sol (TYPE=CORR); INPUT _TYPE_ $ _NAME_ $ idealism rel...
Health Psychologists using questionnaires rely heavily on Cronbach's alpha as indicator of scale reliability and internal consistency. Cronbach's alpha is often viewed as some kind of quality label: high values certify scale quality, low values prompt removal of one or several items. Unfortunately, ...
To verify the reliability and validity of the questionnaire, this paper utilizes SPSS27.0 and Amos24.0 software to conduct the reliability and validity test of the questionnaire. Reliability test Generally, a Cronbach’s α coefficient value of 0.7 or above indicates a good internal consistency of ...
When the participants finished responding to the survey, we gave 2 yuan to each participant as a reward. Measures Internet Addiction Diagnostic Questionnaire The Chinese version of the Internet Addiction Diagnostic Questionnaire (Cronbach’s alpha = 0.84 for this study) was used to measure PIU...
For results sections you’ll generally need to describe how you tested your hypotheses and your main findings. Also, explain how you scored or combined measures or created scales and describe scale reliability (Cronbach’s alpha; α). Organize this section by hypothesis. Communicate with words, ...
In the French validation, reliability is adequate for Attention to other’s feelings (Cronbach’s α = 0.78) and Prosocial actions (Cronbach’s α = 0.81) but limited for Emotion contagion (Cronbach’s α = 0.65). In the present study, Cronbach’s alpha varied from 0.75 to ...
However, coefficients such as Cronbach's Alpha do not indicate the precision with which an individual's performance was measured. Objective Since estimates of precision need to be aligned with the level on which inferences are made, we illustrate how to adequately report the precision of pass-...
we look at Cronbach alpha, Raykov’s reliability, which is typically considered as more accurate (Raykov1997). All of our scales have high Cronbach’s alpha of above 0.8 (Factor 1 =α0,96, Factor 2 =α0,92, Factor 3 =α0,81). Factor 1 (RCC = 0.75) and 2 (RCC = 0.78) also ...
