What is the range if the highest score is 90 and the lowest score is 50?

To determine the range in a set of data, you subtract the lowest score from the highest score. In this case, the highest score is 90, and the lowest score is 50. The calculation would be as follows:

Range = Highest Score - Lowest Score

Range = 90 - 50

Range = 40

This result indicates that the difference between the highest and lowest scores is 40. The range is an important measure in statistics because it provides a quick understanding of how spread out the data values are. Selecting the value of 40 accurately reflects this calculation and provides insight into the variability within the data set.
