Question

Chapter 3, Problem 1CRP

a.

To determine

Identify the measures of variation that indicate spread about the mean.

a.

Expert Solution

Answer to Problem 1CRP

The measures of variation that indicate spread about the mean is standard deviation and variance.

Explanation of Solution

The measures of variation describe the spread of the data. The standard deviation and variance is used to describe the spread of the data around the mean. The standard deviation is based on the difference between each data value and the mean of the data. Moreover, the average spread of the data around the mean is provided by the standard deviation. Hence, the measures of variation indicated spread about the mean is standard deviation and variance.

b.

To determine

Identify the graphic display that shows the median and data spread about the median.

b.

Expert Solution

Answer to Problem 1CRP

The graphic display that shows the median and data spread about the median is box-and-whisker plot.

Explanation of Solution

The spread of the data around the median is identified using box-and-whisker plot. Moreover, the box-and-whisker is created using the five number summary. That is, minimum, first quartile, median, third quartile, and maximum. Hence, the graphic display that shows the median and data spread about the median is box-and-whisker plot.
