The range of scores is a statistical measure that represents the difference between the highest and lowest scores in a data set. It provides a quick sense of the spread or dispersion of scores.
To calculate the range, you simply subtract the lowest score from the highest score. For example, if the highest score in a test is 95 and the lowest score is 60, the range would be:
Range = Highest Score - Lowest Score = 95 - 60 = 35
This means that the scores vary by 35 points. Understanding the range helps in grasping how spread out the scores are, which can be useful for assessing variability in performance.
