Based upon the information shown in this frequency distribution, which one of the following is the value of the class width?

To determine the class width in a frequency distribution, you will typically find the difference between the upper and lower bounds of a specific class interval. The class width represents the range of values that fall within a single class of the distribution.

If the answer indicates that the class width is 3.2, this suggests that the calculation of the class boundaries was likely performed by subtracting the lower boundary of a class from its upper boundary. For instance, if a specific interval runs from 10 to 13.2, the width would be calculated as 13.2 - 10 = 3.2.

Understanding how to calculate class width is crucial for accurately interpreting frequency distributions, as it assists in establishing the scale and the intervals used for representing data. Having a consistent class width is essential for readability and analysis of the data presented in a histogram or frequency table.
