Question

`Correlation and Regression

a) Use the least square equation to predict income given ages=21 & 45 & experience=0 & 5.
b) Compute for multiple correlation coefficient.

Age	31	37	28	42	33	25	35	40
Experience	4	1	5	4	3	3	2	2
Income	35400	41200	45000	40300	36800	43200	41600	38700

Definition Definition Statistical measure used to assess the strength and direction of relationships between two variables. Correlation coefficients range between -1 and 1. A coefficient value of 0 indicates that there is no relationship between the variables, whereas a -1 or 1 indicates that there is a perfect negative or positive correlation.
