You calculate the correlation between height and weight for a simple random sample of 50 students from your college. Another student does the same for a simple random sample of 200 students from the college. The other student should get
A) a correlation greater than 1.
B) a correlation less than -1.
C) a higher value for the correlation.
D) a lower value for the correlation.
E) about the same value for the correlation.

Quizplus · Accepted Answer

Both samples are simple random samples from the same college, so they should provide similar results in terms of the correlation between height and weight. Therefore, the other student should get about the same value for the correlation as you did. Choices A and B are impossible because the correlation coefficient ranges between -1 and 1. Choices C and D are unlikely because the samples are not vastly different in size, so they should not produce drastically different correlation coefficients.
