CORRELATION

Correlation is  the study of the  liner relationship  between  two variable when there is a  relationship of quantitative measures between two set  of variable  the appropriate statistical tool for measuring the relationship and expressing each in a precise way is known  as correlation. For  example  there is a relationship  between  the  heights and  weights of persons demand  and prices of  commodities etc.
