If correlation coefficient between your HW score and your midterm is 0.34, what is this meaning? Please describe as detail as possible. (Question from my statistic professor, dont know how to understand)
Homework Answers
The value of correlation between HW score and your midterm is 0.34, which is positive yet really low.
Hence the HW score and your midterm are positively correlated but the degree of association is low.
