Correlation analysis: The correlation analysis refers to the techniques used in measuring the closeness of the relationship between the variables. The degree of relationship between the variables under consideration is measured through the correlation analysis. And the measure of correlation called as correlation coefficient or correlation index summarizes in one figure the direction and degree of correlation. Thus correlation is a statistical device which helps us in analyzing the covariation
