4. When interpreting a scatterplot, the association must be positive or negative.True
False

Answers

True True True True True True True True 

The correct answer is:

True.

Explanation:

An association between two variables in a scatterplot is shown by most of the points following a pattern.  This pattern can be linear or non-linear.  The more closely the points seem to follow this pattern, the stronger the association.

An association in a scatterplot can be negative, meaning that as one variable increases the other decreases, or positive, meaning that as one variable increases the other increases as well.  A negative association will appear to decrease on a graph, and a positive association will appear to increase on a graph.
