Frequency Distribution Formula

A frequency distribution is the representation of data, either in a graphical or tabular format, to displays the number of observation within a given integral.

In Statistics, a frequency distribution is a table that displays the number of outcomes of a sample. Each entry occurring in the table contains the count or frequency of occurrence of the values within a group.

 

Solved Examples

Example: A survey was taken in Maple Avenue. In each of 20 homes, people were asked how many cars were registered to their households.The results were recorded as follows:

3, 1, 4, 0, 2, 1, 5, 2, 1, 5, 4, 2, 3, 2, 0, 2, 1, 0, 3, 2.

Present this data in Frequency Distribution Table.

Also find maximum number of cars registered by household.

Solution: Divide the number of cars (x) into intervals, and then count the number of results in each interval (frequency).

Thus creating the frequency Distribution Table

 

Number of Cars

Thus, from the table it is clear that the 6 household has 2 cars.
