Card 3 / 7: Which is the best interpretation of a Pearson correlation coefficient of 0.7?
A) For each 1?-unit increase in the exposure variable, we expect a 0.7?-unit increase in the outcome variable.
B) For each 1?-unit increase in the outcome variable, we expect a 0.7?-unit increase in the exposure variable.
C) For each 1?-unit increase in the exposure variable, we expect a multiplicative increase of 0.7 in the outcome variable.
D) For each 1?-unit increase in the outcome variable, we expect the exposure variable rank to increase by a factor of 0.7.
E) There is a moderately strong linear association between the exposure and outcome variables.
