Applications of Scatterplots

Multiple Choice

PARTNER PRACTICE

1. Determine if any, the association between the number of free-throw shots missed and the number of practice shots taken.

REMEMBER: Association is the pattern of the points.

• Non-Linear Association

• Positive Linear Association

• No Association

• Negative Linear Association

Multiple Choice

PARTNER PRACTICE

2. How many free-throws could be expected to be missed by a player that took 16 practice shots?

HINT: Which point would line up with the other points in the data?

• 5 missed free-throws

• 2 missed free-throws

• 8 missed free-throws

• 3 missed free-throws

4. Determine the mean absolute deviation of the number of practice shots taken.

REMEMBER: Use the steps for determining M.A.D. with DESMOS

• M.A.D. = 12

• M.A.D. = 16

• M.A.D. = 30

• M.A.D. = 3.3

Directions: Working with a partner, answer the following problems related to analyzing scatterplots to make predictions and interpreting data sets.
