What three factors affect the size of the correlation coefficient?
What will be an ideal response?
(a) Linearity–If the relationship between two variables is nonlinear, the Pearson Product-Moment Correlation will not give you the best information about the strength of the association.
(b) Restriction in range–If you measured variables over a limited range of their values, the correlation coefficient will be lower than it would be if you used the entire range.
(c) Homogeneity of subgroups–If there are subgroups in the total sample you use and if those subgroups are different from one another, you might wind up with correlations that don't represent the true relationship between variables.
