Difference Between Correlation And Regression

If the regression equations are$\hat{X}=64–0.95y$,$\hat{Y}=7.25–0.95x$ then find the correlation coefficient.

Write any three properties of regression.

Find the standard deviation of $Y$ given that $V\left(X\right)$ is $36$, $b_{XY} = 0.8$, $r_{XY}=0.5$.

Regression analysis helps in establishing a functional relationship between ______ variables.

Arithmetic mean of the regression coefficients $b_{XY}$ and $b_{YX}$ is

Using the regression coefficients we can calculate
