question 29

Multiple Choice

Consider the following scatterplot of two variables x and y. We may conclude:

• A)the correlation between x and y must be close to 1, because there is a nearly perfect relation between them.
• B)the correlation between x and y must be close to -1, because there is a nearly perfect relation between them but it is not a straight line relation.
• C)the correlation between x and y is close to 0 because, although there is a strong relationship between these variables, it isn't a linear relationship.
• D)the correlation between x and y could be any number between -1 and +1; we can say nothing more without knowing the actual values.
