All classes should have the same class width. Calculate the range of the entire data. Suppose we have the following frequency distribution that represents the number of wins by different basketball.
It is calculated as. The class width can be found by finding the difference of the maximum data value and the minimum data value range of data divided by the number of classes. In this video we identify the class width used for a frequency distributionThis video is part of the content available for free at httpswwwstatsprofess.
The width is returned distributed into 7 classes with its formula where the result is 74286. You can calculate the class width by dividing the total range of numbers in your data set by the number of intervals you want to create. N is the number of classes.
