If the highest score in a test is 95 and the lowest is 10, what is the range?

To find the range of a set of scores, you subtract the lowest score from the highest score. In this case, the highest score is 95 and the lowest score is 10.

The calculation would be as follows:

Range = Highest Score - Lowest Score

Range = 95 - 10

Range = 85

This calculation indicates that the spread of scores from the lowest to the highest is 85, which is why the answer is 85. This concept is essential in statistics as it provides a quick sense of the distribution of the data points, reflecting how much variation exists within a set of scores.
