Types of Correlation

For example  heights and weights  income and expenditure of a groups  of individuals prices and supply  of commodities.

2.Negative  Correlation: The values  of two  variables  move  in opposite  directions, so  that with  an increase  in the values  of one variable the value  of the other  variable  decrease and with a decrease in  the values of  one variable  the values of the  other variable increase, correlation is  said  to be negative.
