How to find a class width?
Understand the Problem
The question is asking how to determine the width of a class in a frequency distribution. Class width is calculated by taking the difference between the upper and lower limits of a class or by dividing the range of the data set by the number of classes.
Answer
(max-min)/n
The final answer is that the class width can be determined using the formula (max-min)/n where 'max' is the maximum value, 'min' is the minimum value, and 'n' is the number of groups or classes.

The final answer is that the class width can be determined using the formula (max-min)/n where 'max' is the maximum value, 'min' is the minimum value, and 'n' is the number of groups or classes.
More Information
Class width is essential in constructing histograms and frequency distributions to ensure uniformity in data representation.
Tips
A common mistake is to not ensure that the number of groups is appropriate for the dataset, leading to misleading or overly complex distributions.
