# Average (Mean)

How to find the average (mean) of the given data: formula, examples, and their solutions.

## Formula

The average (mean) is one of the ways

to represent the whole data.

(average, mean) = (Sum)/(Number)

Other ways: Median, Mode

## Example 1

(sum) = 15

(number) = 7

(average, mean) = 15/7

## Example 2

Make a '(Scores)⋅(Frequency)' column

next to the 'Frequency' column.

Write the (scores)⋅(frequency) for each row.

This means adding up the same scores.

(Row 3: 2 + 2 + 2 + 2 = 2⋅4 = 8)

At the bottom,

write the sum of the (scores)⋅(frequency): 60.

This is the 'sum' of the data.

(sum) = 60

(number) = 20

(average, mean) = 60/20
