The following scatter plot of 4 different samples shows the correlation between weight and height in the samples. All 4 samples have the same coefficient of correlation of 0.6 taken together, what will be the net correlation coefficient?
Cannot be calculated
Ans: C. 0.6
- The coefficient of correlation is given by the slope of the graph since the slope of all four populations is the same i.e. 0.6, the overall correlation coefficient will remain as 0.6.
