Represent the set of data in a box plot.

Describe the shape of the distribution.

• The shape of the distribution is not symmetric. There are no outliers.

• The shape of the distribution is not symmetric. There is an outlier.

• The shape of the distribution is symmetric. There are no outliers.

• The shape of the distribution is symmetric. There is an outlier.

Choose the appropriate measures to describe the center and spread of distribution.

• median and interquartile range because the distribution is not symmetric.

• median and interquartile range because the distribution is symmetric.

• median and the outlier because the distribution is symmetric.

• median and the outlier because the distribution is not symmetric.

A value that is much higher or much lower than the other values in a set of data.

• Outlier

• Box Plot

• Range

• Histogram

The heights, in inches, of 12 students are listed below.

59, 60, 60, 61, 61, 62, 63, 64, 65, 67, 70, 86

Which statement best describes the spread of these data?

• The set of data is evenly spread.

• The set of data is skewed because 59 is the only value below 60.

• The median of the data is 59.5.

• 86 is an outlier, which would affect the standard deviation of these data

• Not enough information

What is the effect of a high outlier on the range of a data set?

• It decreases the range.

• It increases the range.

• It has no effect on the range.

• It halves the range.
