Missy played 4 Starmaster games at a video arcade. Her scores were 125, 135, 120, and 140.
What was her median score?

Explanation

To calculate the mean, add all the items together and divide by the number of items.

\(\text { Mean }=\frac{120+125+132+140}{4}=130\)

To find the median, first order the numbers from least to greatest: 120, 125, 135, 140. Find the number(s) in the middle, in this case there are two numbers in the middle, 125 and 135. The mean of those two is the median. Find the sum, 125 + 135 = 260, divide by two 260 : 2 = 130.
