Stats Center Spread and Shape

Which measure of center will be the smallest?

(Remember which one pulls toward the tail)

• median

• mean

• mode

What is the shape of the distribution?

• symmetric

• uniform

• skewed to the right

• skewed to the left

Because this distribution is ____________ to the ___________, we would use the ______________ for the center and the _____________ for the spread of the data.

• symmetric, middle, median, IQR

• skewed, left, median, IQR

• skewed, left, mean, IQR

• skewed, right, median, standard deviation

What is the shape of the data?

• symmetrical

• skewed left

• skewed right

• uniform

Which of the following best describes the shape of the distribution?

• skewed left

• skewed right

• uniform

• symmetrical

Find the IQR of the distribution.

(only type in the number)

The distribution shown is symmetric and we should use the mean and the standard deviation to describe the center and spread.

• True

• False

This distribution is skewed to the ____________.

Find the interquartile range?

• 8

• 6

• 5

• 4

The IQR is the

• max - min

• Interquartile Range

• measure of spread that pairs with the mean

• Q₃ - Q₁
