Cronbach's alpha

been tested in different studies and has shown acceptable levels of Cronbach’s alpha values (Dwyer & Fischer, 1988). The original scale was developed with Canadian athletes and the internal consistency estimates were .83 (training and instruction), .72 (democratic behavior), .45 (autocratic behavior), .70 (social support behavior) and .82 (positive feedback behavior). The internal consistency in this study used the Cronbach´s alpha values of .87 (training and instruction), .61 (democratic…

Test Design and Evaluation Participants Two groups of participants will be recruited; a control group consisting of healthy American soldiers and an experimental group consisting of American soldiers who sustain a concussion. Participation will be voluntary and participants should be free of any history of concussion or cognitive impairment. Due to the disproportionate gender representation of soldiers only men will be included and participants have to be between 18-50 years. The study will…

on two samples of diabetes patients. The reliability or internal consistency of the instrument was determined using Cronbach’s alpha while the construct validity was determined by performing hypothesis tests to confirm the relationships between test scores and related variables (Fitzgerald et al., 2016). The findings of the study showed that the DKT2 instrument is both reliable (alphas ≥ .70) and valid. In this context, the main researcher will use the two instruments to collect data from the…

Difficulties Questionnaire (SDQ), was used to screen children to measure their positive and negative behaviours, results showed good reliability and validity (Goodman, Lamping, & Ploubidis, 2010) and had adequate internal consistency with its Cronbach’s alpha value at 0.76 for internalising problems, 0.72 for externalising problems, and a value of 0.82 for prosocial behaviour. As for parenting style, the over-reactivity and laxness subscales both had good internal consistency with values of ( =…

Annotated Bibliography This annotated bibliography reflects my passion to teach marriage and relationship education classes to adolescents and adults in order to help strengthen the developed relationship skills within the couple unit. These articles cover influences on romantic relationships across the lifespan as well as curriculum evaluations related to the programs I am certified to teach (PREP). This bibliography also includes journal articles about divorce mediation and the effects of…

The SIMS Motivation questionnaire exhibits internal consistency using Cronbach’s alpha levels (p. 6)  Data analysis Data analysis and the results are listed separately in the study. The data analysis is brief, but includes detailed information about how the data was analyzed. All data was analyzed using the Statistical Package for the Social Sciences (p. 7). The results include means, standard deviations, and Cronbach’s alphas for the variables in the study and can be found in table 1 of the…

scale is when a question has two possible responses. A Likert scale is a type of rating scale that measures how someone feels about a certain topic containing degrees of feeling. With multiple Likert questions in a survey Cronbach’s alpha helps measure its reliability. Cronbach’s alpha is computed by correlating the score for each scale item with the total score for each observation, and then comparing that to the variance for all individual item scores. The survey will measure perceptions of…

entrepreneur would mean for you, and considering that Cronbach’s Alpha indicator is the reliability index of the scale, taking into account the 7 variables of the question, the degree of reliability is high. However, it was necessary to eliminate the economic uncertainty variable to assure the reliability, because that question presented a higher result than 0.801 which is the Cronbach’s Alpha (See Table…

In order to examine the data, we utilized SPSS statistical software and conducted a regression analysis of the direct variables of Organizational Citizenship Behavior, Work and Well-being, and Job Satisfaction against the constant independent variable, Frequency of Supervisor Feedback. We used regression analysis because it allowed us to discern any causal relationships between our dependent variables and one constant variable that might support or reject our hypotheses. We were looking for…

2015). Instrument including reliability and validity The reliability and validity of the survey used these instruments, for frequency occurring item analysis, confirmatory principal components analysis and internal consistency reliability using Cronbach’s alpha was used. This article was compiled by scholarly…
