A group of 4 friends likes to golf together, and each friend keeps track of her all-time lowest score in a single round. Their low scores are all between 90and 100 except for Angie, whose low score is 80.

Angie then golfs a great round and has a new low score of 75.

How will decreasing Angie's low score affect the mean and median?

The median will decrease, and the mean will stay the same

To find the median you list out all the numbers and find the middle.

80, 90, 100

With angie getting 75, it goes from "80, 90, 100" to "75, 80, 90, 100"

This changes the median from 90 to 85.

Mean is the average of all the numbers. The average of the first set of numbers (Found by adding all of the numbers up and dividing by the amount of numbers present) is 90.

The mean of the second set is 86.25

The answer would be A, both the mean and median will decrease.
