Practice Range (Statistics) in Math
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
The statistical range is the difference between the maximum and minimum values in a data set: \text{range} = \max - \min.
The range answers "how spread out is the data from end to end?" — it captures the total span but ignores everything in between.
Example 1
easyFind the range of the data set: \{3, 7, 2, 9, 5, 1, 8\}.
Example 2
mediumTwo classes took the same test. Class A scores: \{55, 70, 85, 90, 95\}. Class B scores: \{72, 74, 76, 78, 80\}. Compare the ranges and explain what the difference tells you.
Example 3
easyFind the range of the monthly temperatures (°F): \{32, 45, 58, 72, 85, 90, 88, 75, 62, 48, 36, 30\}.
Example 4
hardA data set has a range of 24. If the maximum value is 3x + 5 and the minimum value is x - 3, find the value of x.
