Practice Median in Statistics
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
The median is the middle value when all data points are arranged in order from smallest to largest. Half the values lie above it and half below. For an even number of values, the median is the average of the two middle values.
If you lined up your whole class by height, the median height is the person standing exactly in the middle. It's not affected by whether the tallest kid is 5'5" or 7 feet - the middle person stays the same.
Example 1
easyFind the median of: 12, 5, 8, 3, 15, 7, 10.
Example 2
mediumFind the median of: 4, 9, 2, 7, 11, 6.
Example 3
easyFind the median of: 20, 35, 15, 40, 25.
Example 4
mediumThe ordered data set is 4, 7, 8, 9, 12, 14, 18. What is the median, and if 30 is added to the set, does the median change?
