Correct answer: (C) Association among variables — The major characteristic of correlation analysis is to seek out association among variables, so that is the answer.
Explanation
★The major characteristic of correlation analysis is to seek out association among variables, so that is the answer.
★Correlation measures how strongly two variables move together.
★So it seeks out the association, the degree to which changes in one go with changes in the other.
★Finding differences among variables is the aim of comparison, not correlation.
★Variation within a variable is measured by dispersion, not by correlation.
★Regression predicts one variable from another, so correlation analysis chiefly seeks association among variables.
