Variance heterogeneity can be problematic for the t test of the Pearson correlation coefficient,especially if one is going to pursue estimation of the:
A)population variance
B)sample correlation coefficient
C)population regression equation
D)population mean

Question

Quizplus · Accepted Answer

Population regression equation involves estimating the relationship between two variables, which requires estimating the population variance and the sample correlation coefficient. If variance heterogeneity exists, then the assumption of equal variances is violated, which may affect the accuracy and validity of the estimation of the population regression equation. Therefore, it is important to address variance heterogeneity before estimating the population regression equation.
