DRP test scores There are many ways to measure the reading ability of children. One frequently used test is the Degree of Reading Power (DRP). In a research study on third-grade students, the DRP was administered to 44 students.32 Their scores were: 40 26 39 14 42 18 25 43 46 27 19 47 19 26 35 34 15 44 40 38 31 46 52 25 35 35 33 29 34 41 49 28 52 47 35 48 22 33 41 51 27 14 54 45 Make a histogram to display the data.

Write a paragraph describing the distribution of DRP scores.
ANSWER:Step 1 of 3
Following are the steps to construct a histogram for the given data:
Divide the data into classes of equal width.
The data varies from 14 to 55. So, classes each of width 6 starting from 14 is chosen.
Calculate the count (frequency) of test scores in each class.
The frequency of scores for each class is mentioned in the table below:
Class |
Count |
14-20 |
6 |
21-27 |
7 |
28-34 |
7 |
35-41 |
10 |
42-48 |
9 |
49-55 |
5 |
Label and scale your axis.
Label the horizontal axis as DRP test scores. The scale on the horizontal axis runs from 14 to 55 because that is the span of the classes chosen. The vertical axis contains the scale of counts.
