Last time we have discussed the concept of regression analysis. Let us discuss the difference between correlation and regression.

CORRELATION
1 ) correlation means relationship between two or more variables.
2) It is only a tool of ascertaining the degree of the relationship between two variables therefore we cannot say that one variable is the cause and other the effect. 4) It is independent of change of scale and origin. 5) It is confined only two the study of linear relationship between variables. |
REGRESSION
1) It means stepping back and returning to average value. It is the measure of average relationship between two or more variables in terms of the original units of data. 2) It indicates the cause and effect relationship between the variables as one variable is taken as dependent while other as independent.
3) There is no such thing like non sense regression. 5) It studies linear as well as non linear relationship between the variables. |

These are the 5 differences between correlation and regression
