Question

the test scores of ms. jacksons 105 students are summarized in the table below. construct and label a frequency histogram of the data with an appropriate scale.
test score num. of students
50 - 59 3
60 - 69 12
70 - 79 51
80 - 89 33
90 - 99 6

Explanation:

Step1: Determine x - axis values

The x - axis will represent the test score intervals: 50 - 59, 60 - 69, 70 - 79, 80 - 89, 90 - 99.

Step2: Determine y - axis values

The y - axis represents the number of students. The maximum number of students is 51. A suitable scale for the y - axis could be 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55.

Step3: Draw rectangles

For the interval 50 - 59, draw a rectangle with height 3 above the interval on the x - axis.
For the interval 60 - 69, draw a rectangle with height 12 above the interval on the x - axis.
For the interval 70 - 79, draw a rectangle with height 51 above the interval on the x - axis.
For the interval 80 - 89, draw a rectangle with height 33 above the interval on the x - axis.
For the interval 90 - 99, draw a rectangle with height 6 above the interval on the x - axis.

Step4: Label the histogram

Label the x - axis "Test Score" and the y - axis "Number of Students". Give the histogram a title, for example, "Test Scores of Ms. Jackson's Students".

Answer:

A frequency histogram with x - axis labeled "Test Score" (with intervals 50 - 59, 60 - 69, 70 - 79, 80 - 89, 90 - 99), y - axis labeled "Number of Students" (with scale 0 - 55 in increments of 5), and rectangles of appropriate heights (3, 12, 51, 33, 6 respectively for the given intervals) and a title such as "Test Scores of Ms. Jackson's Students".
