In your own words describe the information the range provides for a set of scores.

Dispersion

Step-by-step explanation:

Given a set of scores {a1, a2, ..., an} ordered in value, the range can be described as the difference between the highest and the lowest value. We can write it as:

range = an - a1

Thus, the range provides information about the dispersion of our set of values. A high range means that the highest and the lowest value are highly separated, on the other hand, a low range mean that there is a little difference between those values.

This is usually used to measure dispersion on a set of values, together with standard deviation and interquantile range. However, we cannot maintain that one is better than the others.
