Problem

11. Use this situation for the following problem. Over the past nine games, Tina's point total for each game was $14,18,13,18,25,13,2,5$, and 18. Find the median. 13 14 18 15

Solution

Step 1 :Over the past nine games, Tina's point total for each game was 14, 18, 13, 18, 25, 13, 2, 5, and 18.

Step 2 :We need to find the median of these scores.

Step 3 :The median is the middle number in a sorted list of numbers.

Step 4 :If the list has an odd number of observations, the median is the middle number.

Step 5 :If the list has an even number of observations, the median is the average of the two middle numbers.

Step 6 :In this case, we have 9 observations, so we need to sort the list and find the middle number.

Step 7 :Sorting the scores, we get: 2, 5, 13, 13, 14, 18, 18, 18, 25.

Step 8 :The middle number in this sorted list is 14.

Step 9 :So, the median of Tina's point total for the past nine games is \(\boxed{14}\).
