**Scatter plots**are similar to line graphs in that they use horizontal and vertical axes to

**plot**data points. However, they have a very specific purpose.

**Scatter plots**show how much one variable is affected by another. The relationship between two variables is called their correlation .

People also ask, how do you describe the association?

No

**association**: Hard to find a pattern showing a relationship between the variables. STEP 1: Make a scatterplot;**describe**the form, direction and strength of the relationship. Before doing the scatterplot you need to decide which variable is the explanatory variable and which is the response variable.What is a positive association?

**Positive correlation**is a

**relationship**between two variables in which both variables move in tandem. A

**positive correlation**exists when one variable decreases as the other variable decreases, or one variable increases while the other increases.
