What Is Cronbach’s Alpha And How To Calculate
Cronbach's alpha is a widely used measure of internal consistency, which indicates how closely related a set of items are in a group. It involves calculating the average covariance and dividing it by the average total variance, resulting in a high alpha value indicating high reliability. On DATAtab, Cronbach's alpha can be easily calculated online by selecting the desired variables. It is commonly used for assessing the reliability of a set of scale or test items, especially in surveys with multiple Likert questions. To calculate Cronbach's Alpha, responses for up to five questions can be entered into the given boxes. through a simple process.
