the pearson product-moment correlation coefficient, r, requires that variables are measured with? a. interval scale b. ratio scale c. ordinal scale d. a or b
Homework Answers
We know that,
The Pearson product-moment correlation coefficient, r, requires that variables are measured with either interval or ratio scale.
Hence,
Option d. is correct.
