What is correlation coefficient. How does it relate to the validity coefficient? Why are these concepts important to psychological testing?
Homework Answers
Correlation coefficient is a numerical measure or a statistical index for depicting the mutual relation between variables which are either continuous variables or dichotomous variables. The validity coefficient is an index depicting the extent of the correlation between test scores and dependent variable.This also shows the validity for interpretations of test scores that had planned. It helps in understanding the significance of each variable.if one variable change, thereby we can predict the chance of changes in other variable.
