A group of 444 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 909090 and 100100100, except for Angie, whose low score is 808080. Angie then golfs a great round and has a new low score of 757575. How will decreasing Angie's low score affect the mean and median?
The mean (which is the average of all 4 scores) will likely DECREASE since A put in a lower score (if the other scores do not change).
The median (which is the middle of the list scores..... or the average of the two middle scores if their is an even number of entries in the list ) won't change as A is already an outlier and does not change.
