10 1 9. OK so heres our data. 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.

Class Frequency 1 11 3 12 22 6 23 33 4 34 44 2 Class Frequency 1 - 11 3 12 - 22. In this topic we will discuss the. So how do you determine class width.

Simplify to locate the class width is 3. Round up to the next convenient number if its a whole number also round up to. Find the class width.

The definition of class width is. Calculate the class width. In a frequency distribution a class interval represents the difference between the upper class limit and the lower class limit.

As stated the classes must be equal in width. To calculate the class width for a frequency distribution of this dataset we simply need to decide how many classes we want to use. Suppose we want to use n 5.

Find the Class Width of the Frequency Table. Determine the range of the data and divide this by the number of classes. Class width refers back to the distinction between the lower and upper limitations associated with a class category.
