Select all statements that describe the effects on the data set when the water slide with the smallest height would be discontinued. Answer Choices The mean will increase. The mean will decrease. The median will increase. The median will decrease. The mean will stay the same. The median will stay the same.

Answer 1

70, 80, 90, 100, 110
Mean = 90 ft (Add the numbers together, then divide by how many numbers there are)
Median = 90 ft (the middle number)

80, 90, 100, 110
Mean = 95 ft
Median = 95 ft (if there are 2 middle numbers, add them together, then divide by 2)

The mean will increase. The median will also increase.
