Significance of Cronbach's alpha
Cronbach's alpha is a statistical measure used to determine the internal consistency and reliability of items within a questionnaire. It assesses how well the items correlate with each other, providing an indication of how closely related they are as a group. Values above 0.9 indicate excellent internal consistency, while values above 0.80 are considered good. Cronbach's alpha is widely used in research to evaluate the reliability of various questionnaires, with varying reported values reflecting their internal consistency.
