Question

Which statement about a scatterplot with a positive correlation is TRUE?

As the x
-values increase, the y
-values increase.

As the x
-values increase, the y
-values decrease.

As the x
-values decrease, the y
-values increase.

As the y
-values increase, the x
-values increase.

Answer 1

Both statement 1 and statement 4 are true.

A positive correlation means the two variables move together: as x increases, y tends to increase (statement 1), and equivalently, as y increases, x tends to increase (statement 4).
