Boxplots of two data sets are shown.

Based on the boxplots, which of the following is true?

a. The range of both plots is about the same.

b. The means of both plots are approximately equal.

d. The medians are approximately equal.

e. Plot 1 is more symmetric than Plot 2.

Short Answer

Expert verified

Option (a) The range of both plots is about the same is true.

Step by step solution

01

Given Information

We need to find the true statement of the given statements.

02

Explanation for Option (a)

This statement is true because the spread is the distance between whiskers of the boxplot and we note that these are for both plots about same.

03

Explanation for Option (b) 

This statement is false because you can't determine the mean based on boxplot.

04

 Explanation for Option (c) 

This statement is false because you can't find the number of data points based on boxplot.

05

Explanation for Option (d) 

This statement is false because we see that medians are not equal since lines are not in same Position.

06

Explanation for Option (e) 

This statement is also false because the lines of middle in the box is more to the left of box than the Line in the middle in box of plot2.
