Question

The data below shows the scores of some students on a test: 32, 29, 21, 20, 26, 23, 28 Which box plot represents the data? A box and whisker plot is drawn using a number line from 20 to 35 with primary markings and labels at 20, 25, 30, 35. In between two primary markings are 4 secondary markings. The box extends from 21 to 28 on the number line. There is a vertical line in the box at 26. The whiskers end at 20 and 29. Above the line is written Student Scores.

Answer 1

It should look like this .
I believe the last one is correct because 26 is the medium.

Answer 2

Answer:

A box and whisker plot is drawn using a number line from 20 to 35 with primary markings and labels at 20, 25, 30, 35. In between two primary markings are 4 secondary markings. The box extends from 21 to 29 on the number line. There is a vertical line in the box at 26. The whiskers end at 20 and 32. Above the line is written Student Scores.

Step-by-step explanation:

First we order the data from least to greatest:

20, 21, 23, 26, 28, 29, 32

We find the median, which is the middle value, next.  It is 26.

The median "splits" the data into an upper half and a lower half.  The first quartile, Q1, is the middle of the lower half; this is 21.  The third quartile, Q3, is the middle of the upper half; this is 29.

The box in a box and whisker plot will have sides at Q1 and Q3; there will be a vertical line at the median, 26.

The whiskers will go from the right side of the box to the highest value, 32, and from the left side of the box to the lowest value, 20.
