Correlation:-
Bi-variate distribution– simple correlation – meaning – assumptions – positive and negative correlation – scatter diagram – computation of correlation coefficient – properties of correlation coefficient – testing and interpretation of correlation coefficient – coefficient of determination.
Regression:-
Regression – simple linear regression – meaning – assumptions – fitting of simple linear regression equation of y on x – properties of regression coefficient – testing and interpretation of regression coefficient and intercept. Multiple linear regression – assumptions – difference between simple and multiple linear regression – standardised and partial regression coefficients – fitting of multiple linear regression equation – testing the regression coefficients – interpretation of regression coefficients – multiple correlation – coefficient of multiple determination
