Sta301 GDB Idea Sol

“If coefficient of correlation, “r” between two variables is zero, does it mean that there is no relationship between the variables? Justify your answer”.

Solution:-
If there is no linear correlation or a weak linear correlation, r is close to 0. A value near zero means that there is a random, nonlinear relationship between the two variables. The change in one variable will not affect other variable. There is no relationship between the variables.
