QuestionFind the grouped frequency distribution for these test scores: 83, 85, 97, 91, 92, 82, 90, 89, 91, 83, 93, 88, 86, 84, 98. Class width is 5. Then, draw a frequency polygon with midpoints labeled.

Studdy Solution
Now that we have the midpoints for each class, we can plot the frequency polygon. On the x-axis, we plot the midpoints of the classes. On the y-axis, we plot the frequencies of the classes. Connect the points with straight lines to form the frequency polygon.
