Question

A frequency table consists of -

• A. data points/ categories
• B. frequencies of the data points/ categories
• C. (a) and (b) above.
• D. None of the above.

Answer 1

The correct option is C (a) and (b) above.

A frequency table consists of both the data points/ categories and their frequencies.

Consider the following data points of the number of kilometers traveled by Janifer: $9,1,8,7,8,1,9,2,8$

We plot the frequency table by noting down the number of times each number occurs.

For example, $9\text{km}$ is occuring twice.
$\therefore$ The frequency correcponding to $9\text{km}$ is $2.$

The frequency table of the data set is as follows: Distance Travelled (km) Frequency

$1$	$1$
$2$	$1$
$7$	$1$
$8$	$3$
$9$	$2$
