r = correlation between two variables in the sample (rho) = correlation Testing for the significance of the correlation coefficient, r. When the test is against the null hypothesis: r xy = 0.0. What is the likelihood of drawing a sample with r xy ­ 0.0? The sampling distribution of r is . approximately normal (but bounded at -1.0 and +1.0) when N is large; and distributes t when N is

Coefficient of correlation is “R” value which is given in the summary table in the Regression output. R square is also called coefficient of determination. Multiply R times R to get the R square value. In other words Coefficient of Determination is the square of Coefficeint of Correlation. R square or coeff. of determination shows percentage variation in y which is explained by all the x
