For which classifications of data can you use the Pearson product-moment correlation technique to calculate a correlation coefficient? A. When both variables are measured on an interval or ratio scale B. When both variables are measured on an ordinal scale C. When both variables are measured on a nominal/dichotomous scale D. When one variable is measured on a nominal/dichotomous scale, and one is measured on an interval or ratio scale E. You cannot use the Pearson product-moment correlation technique to calculate a correlation coefficient
