Recognizing Scatter Plots

Based on the data of the scatter plot, what would you expect the sales to be when it is 20 degrees?

• 400

• 500

• 450

• 350

A new smartphone game deducts points from your account when you purchase tokens within the game. If you purchase a large number of tokens at one time, the game deducts fewer points from your account overall. The scatter plot below displays data for eight users' accounts. The relationship between the number of tokens purchased is displayed on the x-axis and the number of points deducted is displayed on the y-axis.

Which of the following statements correctly describe the scatter plot shown? Select ALL that apply.

• There are no outliers.

• The scatter plot shows a linear association.

• The scatter plot shows a positive association.

• The scatter plot shows no association.

• The scatter plot show a negative association.

Which scenario would most likely show a negative association between the variables?

• the height of a tree, x, and the amount of time it takes to climb to the top of the tree, y

• the number of people in the mall, x, and the number of cars in the parking lot, y

• miles traveled in a car, x, and the amount of gasoline used, y

• time spent reading a book, x, and the number of pages left to read, y

The scatter plot shows the sizes and annual rents of some office spaces in the downtown area of a city.

What would the line of best fit reveal about these data?

• There is a strong negative relationship between the cost of rent and the size of the office space.

• There is a strong positive relationship between the cost of rent and the size of the office space.

• There is a weak positive relationship between the cost of rent and the size of the office space.

• There is a weak negative relationship between the cost of rent and the size of the office space.

A scatter plot for calories burned and minutes of exercise is drawn. Observe the graph carefully and identify the outliers present.

• (140,150)

• (150,140)

• (180,450)

• None of these

In the scatter plot for calories burned and minutes of exercise (the same one from question six), what is the context of the outliers present?

• The person who exercised for 140 minutes burned 150 calories.

• The person who exercised for 150 minutes burned 140 calories.

• The person who exercised for 180 minutes burned 450 calories.

• Not applicable - there is no outlier.

Find the equation of the line of best for the scatter plot given below.

• y = x - 5

• y = x + 5

• y = 2x - 5

• y = 2x + 5
