Mode and Mean from Frequency Table

In this lesson, we will look at obtaining the mode and the mean from a frequency table.

Mode from frequency table

Example:

Find the mode of the following set of marks.

Solution:

The marks 2 and 3 have the highest frequency. So, the modes are 2 and 3.

The above example also shows that a set of observations may have more than one mode.

Mean from frequency table

If the data is summarised in a frequency table, we use the following formula to find mean:

Example:

The table shows the marks obtained by a group of players in a game. Find the mean of the marks.

Solution:

To calculate the mean, we first add the following values to the frequency table:

Then, we calculate the mean using the formula

The following video shows how to obtain the mean, median and mode from frequency table.
