Heights The boxplot shown below results from the heights (cm) of males listed in Data Set 1 鈥淏ody Data鈥� in Appendix B. What do the numbers in that boxplot tell us?

Short Answer

Expert verified

The boxplot shows the following characteristics of the data:

  • The minimum value of the male heights is equal to 155 cm.
  • The maximum value of the male heights is equal to 193.3 cm.
  • The first quartile is equal to 169.1 cm.
  • The median male height is equal to 173.8 cm.
  • The third quartile is equal to 179.4 cm.

Step by step solution

01

Given information

A boxplot is plotted for a dataset containing the heights of males in cm.

02

Interpreting boxplot

Aboxplotis a graphical representation of the five key characteristics of a dataset.

  • The boxplot extends from the minimum value of the data to the maximum value.
  • The leftmost vertical bar of the box in the center represents the first quartile.
  • The middlemost bar represents the median value or the second quartile.
  • The rightmost bar of the box in the center represents the third quartile.
03

Interpretation of the given boxplot

Here, theminimum value denoted by the whisker on the left is equal to 155 cm, and themaximum value denoted by the whisker on the right is equal to 193.3 cm.

The leftmost bar of the box in the middle is thefirst quartile with a value equal to 169.1 cm.

The middle bar of the box is themedian/second quartile with a value equal to 173.8 cm.

The rightmost bar of the box in the center is thethird quartile with a value equal to 179.4

Resistant Measures Here are four of the Verizon data speeds (Mbps) from Figure 3-1: 13.5, 10.2, 21.1, 15.1. Find the mean and median of these four values. Then find the mean and median after including a fifth value of 142, which is an outlier. (One of the Verizon data speeds is 14.2 Mbps, but 142 is used here as an error resulting from an entry with a missing decimal point.) Compare the two sets of results. How much was the mean affected by the inclusion of the outlier? How much is the median affected by the inclusion of the outlier?

Range Rule of Thumb for Interpreting s The 20 brain volumes (cm3 ) from Data Set 8 鈥淚Q and Brain Size鈥� in Appendix B have a mean of 1126.0 cm3 and a standard deviation of 124.9 cm3. Use the range rule of thumb to identify the limits separating values that are significantly low or significantly high. For such data, would a brain volume of 1440 cm3 be significantly high?
