The mean of statistical data is:

Options

• \[ \frac{\text{The highest score} + \text{The lowest score}}{2} \]

• \[ \frac{\text{Total no. of scores}}{\text{The sum of all scores}} \]

• \[ \frac{\text{The sum of all scores}}{\text{Total no. of scores}} \]

The mean is found by dividing the sum of all scores by the total number of scores. This gives the arithmetic average of the data.
