Answer 2

The correct option is (A) Lowering the mean.

Explanation:

• The arithmetic mean is the average quantity in a set of data. It is defined as the total of all observations in the data divided by the number of observations in the data.
• As a result, because the mean comprises all of the data in a series, it is influenced by the extreme values so elimination of extreme value will lead to decrease in mean value.
