Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Statement 1 is true, that is the coefficient of correlation will have the same sign as the regression coefficient as that of the regression coefficients, such as if the regression coefficients have a positive sign, then “r” will be positive and vice-versa. Statement 2 is true that is the arithmetic mean of the regression coefficient is always more than the correlation coefficient statement 3 is false as regression coefficient are independent of change of origin but not change of scale statement 4 is also true as the multiple correlation coefficient, which is often denoted by R, is the square root of the coefficient of determination. Hope that helps. Thank you. 😊
