Direct mean is the addition of all the data values multiplied by the size of the whole population or the size of a sample. True or false

The statement is **false**.

The **mean** (or average) is calculated by dividing the **sum of all data values** by the **size of the population** or **size of the sample**, not by multiplying the sum by the size. The correct formula for the mean is:

\[
\text{Mean} = \frac{\text{Sum of all data values}}{\text{Number of data values}}
\]
