Define the Pearson’s product moment correlation coefficient (Pearson’s r) and the three assumptions that must be met with respect to data for it to be employed.
What will be an ideal response?
? Pearson’s product moment correlation coefficient shows the relationship between two or more interval level variables.
? (1) They must be of interval level measurement.
? (2) If the joint frequency distribution were to be plotted, the relationship would be linear or resemble a straight line. If the relationship is nonlinear, such as curvilinear, then other statistical measures must be used.
(3.) The deviations of points from this line must be relatively uniform (homoscedastic) or demonstrate equal variance.
