The mean of a sampling distribution of r is approximately equal to r.

Question

Quizplus · Accepted Answer

This statement is true. The mean of a sampling distribution of r is expected to be equal to the population correlation coefficient, which is denoted by the symbol ρ. However, when the sample size is large, the sample correlation coefficient r becomes an unbiased estimator of ρ, and its mean is approximately equal to ρ. Thus, the mean of a sampling distribution of r is approximately equal to r when the sample size is sufficiently large.
