Textbook Problem

A set of scores ranges from a high of X = 96 to a low of X = 27. If these scores are placed in a grouped frequency distribution table with an interval width of 10 points, the top interval in the table would be ___________.

  1. a. 90–99
  2. b. 90–100
  3. c. 91–100
  4. d. 87–96

To determine

To find: The top interval of the grouped frequency distribution table.

Explanation

Given info:

Set of scores ranges from a high of X=96 to a low of X=27 and interval width of the distribution table is 10 points.

Reason for correct answer:

The bottom score should be a multiple of class width as the class width is given as 10, so the top interval should start from multiple of 10. Due to this reason top interval in the table would be 90-99, also this interval start from 90 and the class width of this interval is 10
