Use the histogram to the left to check all of the true statements.

• The mean is the best measure of center to represent the graph

• The graph is skewed to the left

• The graph is skewed to the right

• The median is the best measure of center to represent the graph

CCSS.HSS.ID.A.2

Check all that apply regarding the box plot

• 75% of the data points fall between 5 and 9.

• The best measure of center on symmetrical data is the mean

CCSS.HSS.ID.A.2

Given the data set shown below which measure of center is best?

45, 50, 47, 52, 25, 49, 49

• The median 49 best represents the data because the data is skewed left.

• The mean 48.7 best represents the data because the data is symmetrical.

• The median of 49 best represents the data because the data is skewed right

• The mean of 48.5 best represents the data becasue the data is symmetrical

CCSS.HSS.ID.A.2

Given the data set shown below, which measure of spread should be used to describe what is typical?

45, 50, 47, 52, 25, 49, 49

• The IQR because the data is skewed.

• The standard deviation because the data is skewed.

• The standard deviation because the data is normal.

• The IQR because the data is normal.
