Step 1
In this question, we have to tell which option is correct about the correlation study,
Step 2
A correlation coefficient is a method to measure how two variables are related to each other and also what kind of relationship is there between these two variables. Correlation study is helpful when the data is in numerical form and for the categorical form data, we use the chi square distribution access the association. Correlation does not compare the means of two or more groups as well it does not manipulate the independent variables. Therefore, Option A is correct “assess the association between two interval measures”
Step 3
Option A is correct “assess the association between two interval measures”
