How to find class width for a histogram

Answer 1

To find the class width for a histogram, subtract the starting value from the ending value to get the range, and then divide it by the number of intervals.

Step-by-step explanation:

To find the class width for a histogram, you need to determine the range of the data values and divide it by the desired number of intervals, also known as classes. The class width represents the width of each bar or interval in the histogram. Here's an example:

1. Given a range from 32.5 to 100.5 and 5 intervals, subtract the starting value from the ending value to get the range: 100.5 - 32.5 = 68
2. Divide the range by the number of intervals: 68 / 5 = 13.6
3. The class width is 13.6, which represents the width of each bar or interval in the histogram.
