The number of members in 50 households of a village are listed below.

Make a frequency table and answer these questions:

How many households have just two members?

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 number of members in 50 household of a village is given.

Now,

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

To find: Count of households having only 2 members.

Please check in the first column ‘Number of members’ and search for 2.

Now, once you have found number 2, look at the adjacent cell which is 5.

⇒ There are 5 such households having only 2 members.

Here, 5 is called frequency of 2.

Thus, answer is 5.
