The scores of 35 children in a test are given below:

Make a frequency table and answer these questions:

How many children scored 20?

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 scores of 35 children in a test.

Now,

Note that, after making frequency table we can easily answer the questions that follows:

To find: Number of children who scored 20.

Look at the first column ‘Scores of children’ of the table and locate 20.

Now, you need to note the value in the adjacent column, here it is 1.

⇒ 1 student is there who scored 20.

Thus, answer is 1.
