The correct answer is: The range.

Explanation:

The range is one of the measures of variability that are used when reflecting the spread or dispersion in a particular set of data.

The other two measures of variability are the standard deviation and the variance.

The range can be understood as the difference that exists between the lowest number or value and the largest number or value in a particular group or set of values.

For example:

Between (2,4,6,8,10,12,14,16,18...) the range is: 18-2 or: 16.

In conclusion, The three measures of variability commonly used to reflect the spread or dispersion in a group of scores are the standard deviation, the variance, and the range.
