The test scores of six students in a mathematics quiz are $12$ , $18$ , $25$ , $31$ , $47$ , and $50$ . What is the range of these scores?

The range of the scores is

38

The range is a measure of dispersion defined as the difference between the maximum value (

50

) and the minimum value (

12

). Subtracting

12

from

50

gives

38

Identify the maximum and minimum values in the dataset.

Maximum score =

50

, Minimum score =

12

Range measures the spread between the highest and lowest values in a distribution.

Calculate the range using the formula

\text{Range} = \text{Maximum} - \text{Minimum}

\text{Range} = 50 - 12 = 38

Subtracting the minimum value from the maximum value yields the measure of dispersion known as range.
