In statistics, what does the term Range refer to?

• A. The middle value
• B. All the numbers in the set
• C. The most frequent value
• D. The average value

Answer: (B)

The main idea here is understanding how spread in a data set is described. Range is a measure of how spread out the numbers are by looking at the distance between the smallest and largest values. To find it, subtract the smallest value from the largest value: Range = max − min. For example, if your data range from 3 to 17, the range is 14. This is different from the median (the middle value), the mode (the most frequent value), or the mean (the average). Saying “all the numbers in the set” refers to the data itself, not a single summary of spread.
