Class Width Formula
The following equation can be used to calculate the class width of a data set.
CW = (M – m)/n
- Where CW is the class width
- M is the maximum value
- m is the minimum value
- n is the total number of classes.
Class Width Definition
Class width is defined as the difference between the upper and lower bounds of a class or category.
Class Width Example
How to calculate class width?
- First, determine the maximum value.
Calculate the maximum value of the class.
- Next, determine the minimum value.
Calculate the minimum value of the class.
- Next, determine the total number of classes.
Calculate the total number of classes.
- Finally, calculate the class width.
Finally, use the equation above to calculate the class width.
The class width is the difference between the upper and lower bounds of a class or category. These upper and lower bounds are often referred to as the maximums and minimums.
The class width is calculated by subtracting the minimum value from the maximum value and dividing it by the total number of classes.
The max and min values are the largest and smallest values in the data set.
