Scatter Plots Study Guide

What type of association does this scatter plot represent?

• positive linear association

• negative linear association

• no association

• nonlinear association

• cost of the phone bill

• cost of the heating bill

• distance the parking is from the building

• number of pets allowed

For the scatter plot, label the association as positive, negative or none, linear, non-linear. Check all that apply....reminder, for linear ONLY you would determine positive or negative.

• Positive

• Negative

• No Association

• Non-Linear

Compare the scatter plots in #5 and #7. Which has a stronger association? Explain.

• 5 is stronger because it is negative

• 7 is stronger because it is positive

• 5 is stronger because the points are closer together

• 7 is stronger because the points are further away from each other

The scatter plot shows the number of steps a person walked and the number of hours of TV a person watched on a given day.

Does the data demonstrate positive, negative or no association?

• Positive because as the number of TV hours increase, the steps walked increases.

• Negative because as the number of TV hours increases, the steps walked decreases.

• No association because there would be no impact on how much TV a person watches in a day and the number of steps they walk.

Graph the scatter plots for Question 16 and describe any conclusions.

• The negative association shows that as the kilowatt hours increase, the total cost of the electricity bill decreases.

• There is no association

• The positive association shows that as the kilowatt hours increase, the total cost of the electricity bill increases.

What is an equation for the line of best fit?

• y = 25x + 225

• y = -25x + 225

• y = -25x - 225

• y = 25x - 225
