4, 6, 8, 8, 15

The median would decrease

The median would increase

The mean would increase

The mean would decrease

Answer 1

If Lindsay includes the number 23 in the list, the mean would increase. The median, on the other hand, would stay the same because when an outlier is added to a list of numbers, it does not affect the median.
