Question

Quizplus · Accepted Answer

Cronbach's alpha is commonly used to determine internal reliability as it measures how closely related a set of items in a test or scale are to each other. It assesses the degree to which each item in the scale contributes to the reliability and consistency of the overall measure. The other options (B, C, and D) are not used for measuring internal reliability. Kappa is used to measure inter-rater reliability, a scatterplot is a visual tool used for exploring relationships between variables, and Pearson's r is a measure of linear correlation between two continuous variables.
