In Calculating the Pearson Correlation Coefficient, We Assume That

Multiple Choice

In calculating the Pearson correlation coefficient, we assume that:

A) when the correlation coefficient is weak, there is a consistent, systematic relationship between the two variables.
B) the relationship we are trying to measure is curvilinear.
C) the variables we want to analyze have a binomially distributed population.
D) the variables have been measured using interval- or ratio-scaled measures.
E) when the correlation coefficient is strong and significant, the two variables are associated in a curvilinear fashion.
