Practice Range in Statistics
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
The difference between the maximum and minimum values in a data set, measuring overall spread.
Range tells you how spread out your data is from end to end. If the tallest kid is 5 feet and the shortest is 4 feet, the range is 1 foot - that's the 'stretch' of heights.
Example 1
easyFind the range of the data set: 15, 8, 22, 3, 17.
Example 2
mediumTwo basketball players' points per game — Player A: 10, 12, 11, 13, 9. Player B: 5, 20, 8, 18, 4. Who is more consistent?
Example 3
easyThe ages of children at a party are: 6, 9, 7, 11, 8, 10. What is the range of ages?
Example 4
easyMorning temperatures for five days are 12, 13, 12, 14, and 25. What is the range, and what does the day with 25 tell you about the data?
