Abstract

Cronbach’s alpha is commonly used in statistics to measure reliability of tests. Reliability of any measuring instrument/questionnaire refers to the extent to which it measures consistently. Cronbach’s alpha is one of the way of measuring the strength of that consistency. This article is intended to highlight its use in dental research by creating an understanding of Cronbach’s alpha by giving suitable example.
