Question

The dot plot represents the scores of a group of students on an English test. If the dot plot is converted to a box plot, the first quartile would be drawn at, and the median would be drawn at.

1. The first quartile would be drawn at 3 and the median would be drawn
at 4.
What is the median in math?
• The median is the middle number in an ordered data set.
• The mean is the sum of all values divided by the total number of values.
Scores of group of students                        Frequency
1                                                           0
2                                                          2
3                                                          2
4                                                          4
5                                                          3
6                                                          1
7                                                          1
First three set of scores from 1 to 3 comes under first quartile.
Median is in the center.
Last three set of scores comes under third quartile.
Therefore, the first quartile would be drawn at 3.
And the median would be drawn at 4.
