Frequency Distribution Calculator

Top
Frequency is the number of occurrence. Frequency distribution is an ordering of the data values in a data set as per the frequency of the values in an interval. This online frequency distribution calculator will distribute the data values in ascending order as per their frequencies.

Step 1 : Observe the problem and arrange the given data in ascending order.

Step 2 : Find the frequency of each data value. Arrange them and express it in tabular form followed with their frequencies i.e, frequency distribution table.

Problems

Below are some of the problems based on frequency distribution.

Solved Examples

Question 1:
Over the last 10 days, number of newspapers were sold in a shop as given below. Calculate the frequency distribution. 
22, 20, 18, 23, 20, 25, 22, 20, 18, 20

Solution:
Given data : 22, 20, 18, 23, 20, 25, 22, 20, 18, 20

Let's arrange the data in ascending order.
Therefore, the given data is 18, 18, 20, 20, 20, 20, 22, 22, 23, 25.

Step 2 : The frequency distribution of the given data is :
Paper sold Frequency
     18         2
     20         4
     22         2
     24         1
     25         1

The frequency distribution is {{18, 2},{20, 4},{22, 2},{24, 1},{25, 1}}.

Question 2:
A survey was taken in each of 20 houses, they asked how many cars were registered in their house. The survey shows the following result:
1, 2, 1, 0, 3, 4, 0, 1, 1, 1, 2, 2, 3, 2, 3, 2, 1, 4, 0, 0

Solution:
Given data: 1, 2, 1, 0, 3, 4, 0, 1, 1, 1, 2, 2, 3, 2, 3, 2, 1, 4, 0, 0.
Let's arrange the data in ascending order.
Therefore, the given data is 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 4, 4.

Step 2 : The frequency distribution of the given data is : 
Numbers of cars  Frequency 
 0 4
 1  6
 2
 3  3
 4

The frequency distribution is {{0, 4},{1, 6},{2, 5},{3, 3},{4, 2}}.
