Textbook Problem

If the scores in the previous question were placed in a grouped table with an interval width of 5 points, what are the apparent limits and the real limits for the bottom interval?

To determine

To Find: The apparent limits and the real limits for the bottom interval.

Explanation

Given info:

The scores are, 39, 41, 37, 16, 44, 20, 34, 39, 42, 24, 51, 22, 35, 18, 46, 53, 19, and 26.

The width of the interval is 5.

Calculation:

The lower score is 16 and the upper score is 53.

The range of the score is,

Range = Upper value - Lower value=5316=37

The lower and upper class boundaries are obtained by subtracting 0.5 from lower class limit and add 0.5 to the upper class limit
