Range is defined as?

• A. The difference between the highest and lowest scores in a distribution
• B. The average value
• C. The median of the data
• D. The standard deviation of the data

Answer: (A)

Range measures how spread out a data set is by subtracting the smallest value from the largest value. This simple calculation shows how far apart the extreme scores are, giving a quick sense of the overall spread. It focuses on the tails rather than the center, which is why it differs from measures of central tendency like the average or median. It also contrasts with the standard deviation, which describes how far values typically lie from the mean across all data points, not just the endpoints. For example, in a set like 2, 3, 3, 3, 100, the range is 98, highlighting a large gap at the high end, while the mean and standard deviation describe different aspects of the data’s distribution. In short, range is max minus min.
