Purpose
Compute content validity ratio for test items.
Interpret a validity coefficient, calculate the coefficient of determination, and conduct a test of significance for a validity coefficient.
Examine the convergent and discriminant evidence of validity.
In this assignment, you will compute and interpret the validity evidence. In Part 1, you will calculate the content validity ratios. In Part 2, you will compute a validity coefficient using Jamovi. In Part 3, you will conduct a correlation analysis in Jamovi to obtain the convergent and discriminant evidence of test validity.
