Assume that you have 125 observations on the height (H)and weight (W)of your peers in college. Let ${ } ^ { S } H W$ = 68, ${ } ^ { S } H$ = 3.5, $\text { SW }$ = 29. The sample correlation coefficient is
A)1.22
B)0.50
C)0.67
D)Cannot be computed since males and females have not been separated out.

Quizplus · Accepted Answer

The sample correlation coefficient is a measure of the linear association between two variables, and it ranges between -1 and 1. A value of 1 indicates a perfect positive correlation, 0 indicates no correlation, and -1 indicates a perfect negative correlation. The sample correlation coefficient between height and weight in this scenario is 0.67, which indicates a moderate positive correlation. Choice D is incorrect because whether the individuals are male or female is not relevant to calculating the correlation between height and weight.
