The heights (in centimeters) of 45 people who look part in a physical fitness test are given below.

Make frequency table.

First let us understand what frequency table is and why it is made.

The table that is constructed based on the data values with its corresponding frequency is termed as frequency table. Frequency of a data is nothing but the number of times the data value occurs.

We make frequency table for ease of observation.

Let us try making frequency table using the values given in the question…

First, look at what is already given in the question. That is, the height of 45 people who took part in a physical fitness test.

Try to list the numbers in an order (either ascending or descending), this will make our frequency table presentable and neat.

Now,

This is the frequency table we want.
