The class width calculator evaluates the class width for a frequency distribution of the statistical data. Class width analysis with the class boundaries calculator provides understandable information from the whole population.

The class width refers to the difference between the upper & lower boundaries of the sample values. The class width is especially used to identify the range and mean of the dataset to make the data more meaningful.

The class width calculator is meaningful when dealing with a large population to identify the range of the dataset values. The class width analysis is critical to know the maximum and minimum consumers for retail outlets in similar conditions.

To identify the difference between the upper and lower boundaries of two consecutive classes, use the formula below:

**Class width = (Max-Min) / n**

**Where:**

**max = upper boundary of class**

**min = lower boundary of class**

**n =Â number of classes**

The class width should not be mingled with differences between the upper and lower limits of a class. To avoid confusion use the lower and upper class limit calculator to identify the class limit.

Let’s suppose there are different marks obtained by the students of 5 classes. Then identify the reasonable class of marks of students.Â

**52, 82, 86, 83, 56, 98, 71, 91, 75, 88, 69, 78, 64, 74, 81, 83, 77, 90, 85, 64, 79, 71, 64, and 83.**

Max = 98Â

Min= 52

Range of classes =46

n = 5

Class width =?

Class width = (Max-Min) / n

Max â€“ Min =Â 98 â€“ 52Â

Max â€“ Min = 46

NowÂ

Class width =Â (Max-Min) / n

Class width =Â (46) / 5

Class widthÂ = 9.2

Round this number up = 9.2â‰… 10.

The class limits calculator finds the values in the whole numbers.

There are a number of steps in calculating the class width

- Find the upper and lower boundaries of data
- Calculate the range of the entire data
- Find the number of classes
- Divide the Range by the number of classes
- Round the number to the nearest whole numberÂ Â

You may utilize a class width calculator toÂ analyze the data and its class width, respectively.Â

It is easy to calculate class width with our class boundary calculator.

Let’s learn how!

**Input:**

- Enter the minimum and maximum class boundaries
- Enter the number of classesÂ
- Tap
**calculate**Â

**Output:**

- Class width
- Step-by-step calculation

The class width is the difference between the lower limits of two consecutive classes or the upper limits of two consecutive classes.

Class size is the difference between the upper limit and the lower limit of a class interval. It is also known as class width.

The numerical figures used to specify the lower and upper limits of a ‘class interval’ are called class limits.

Frequency is the statistical data and it can be in the form of a positive number or Zero but it can’t be a negative number.

Frequency density is actually the frequency per unit of data in each class which is calculated by dividing the frequency by the class width.

- Class limits are the smallest and largest observations (data, events, etc.) in each class. Therefore, each class has two limits: a lower and an upper.Â
- Class interval is the difference between the upper and lower class boundaries of any class. Class intervals are generally equal in width and are mutually exclusive.
