## LO: To calculate the mean, median, mode and range for a set of data from a frequency table.

• ### I can calculate the mode of a set of data from a frequency table.

#### One quick way to organise data collected is the use of a frequency table (tally table). This methodology helps us to arrange the collected data into a much easier to interpret way.

## Mean

#### Mean = 6.17 (rounded to 2 decimal places)

[/fusion_text][fusion_text]

## Median

#### So the median of this data set would be 6.5.

[/fusion_text][fusion_text]

## Mode

#### Mode is also known as the “most popular/common” number/item. In this data set it would be the most tallied number, which is 7 as it has 6 tallies.

[/fusion_text][fusion_text]

## Range

#### The highest (maximum value) is 10, the lowest (minimum value) is 1. So the range of this data set is 9.
