If the correlation between variable A and variable B is 0, then

Question

Quizplus · Accepted Answer

If the correlation between A and B is 0, it means there is no linear relationship between the two variables. This does not necessarily mean there is no relationship at all, but it does mean we cannot use measurements of A to predict measurements of B with high accuracy. It also does not imply that increases in one variable are associated with increases or decreases in the other variable, as there may be other types of relationships that are not captured by correlation. Therefore, the best answer is C, which states that the relationship between A and B is random. It is also not necessarily true that the mean value of A is equal to the mean value of B, as this depends on the specific distribution of the variables.
