What is the likely effect if the analyst decides to include the lower outlier in the calculations?The median will remain about the same, but the mean will decrease.The median will decrease, and the mean will increase.The mean will stay about the same, but the median will decrease.The median and mean will both stay about the same.
Answer
A
The median will remain about the same, but the mean will decrease.
B
The median will decrease, and the mean will increase.
C
The mean will stay about the same, but the median will decrease.
D
The median and mean will both stay about the same.
Explanation
A lower outlier is much smaller than the other values, so including it pulls the mean downward. The median depends on the middle value or values in the ordered data, so adding one unusually low value generally leaves it about the same. Therefore, the correct choice is “The median will remain about the same, but the mean will decrease.”
