A student has taken five algebra tests already this year. Her scores were 85, 61, 72, 85, and 92. What is the median of those values?
- A. 78
- B. 31
- C. 83
- D. 85
Correct Answer: D. 85
Explanation
To find the median of a set of values, simply place the numbers in order and find the value that is exactly in the middle. Here, we can place the test scores in ascending order to get 61, 72, 85, 85, 92. (Descending order would work just as well.) The median is the middle value, 85. Make sure you don't confuse median with mean (average)! To get the mean value of this set, you would find the sum of the test scores and then divide by the number of values.
