A list of match totals calls for a median: the middle value after the totals are put in order. With an odd number of matches, there is one middle position. For an unordered list, enter every score in a Desmos list and use its median function. Keep repeated scores because each one represents a separate match.
Hints
- Hint 1
The median is the middle value after ordering the scores, not necessarily the middle entry as the list is printed. With an odd number of scores, how many will sit on each side of the middle?
- Hint 2
A repeated score still counts as another match. Enter every score in one Desmos list, including repeats, then use the median function to find the middle of that list.
Step-by-step
Find the middle with a Desmos list
Step 1Locate the middle position
A median is the middle value once the scores are ordered. There are nine matches, so four scores sit on each side of the middle. Its position is the fifth score. With an odd number of scores, take one middle value, not the average of two.
- Step 2
Enter every match score
Type as a Desmos list. Keep each repeat: the three s and three s each represent three different matches. Desmos shows all nine entries, including the repeats. You'll use this list to find the middle score.
- Step 3
Read the median
Type . Desmos shows as the median. That's the fifth score when the nine scores are ordered. So the median is goals per match. Choice C.
