Constructing and Interpreting Scatter Plots

Graph shows the number of people painting a room and the time it takes to paint the room,

True or False:

As the number of people painting decrease, the time it takes to paint the room increases.

• True

• False

The scatter plots represents different types of cruise lines and the total cost. Are there any outliers in the data? Explain.

• Yes, the point (5,500) is an outlier.

• Yes, the point (4,720) is an outlier

• No outliers on the scatter plot.

The scatter plots represents different types of cruise lines and the total cost.

Are there any clusters in the data? Explain.

• No, there are not any distinct or separate groups of data.

• Yes, there is a group between 2 - 3 days

An ​ (a)   is a point that does not fit the overall pattern or trend of a scatter plot.

• outlier

• cluster

Chang wants to know if he is improving his skill on the cello. He created a scatter plot and drew a line of best fit. If he uses the point (2, 8) and (5, 1.5) from his line, which equation would best represent the line of best fit?

• y = -2.17x + 12.3

• y = 2.17x + 3.77

• y = -0.46x + 9

• y = -2.17x – 9.35
