Answer 2

Answer:

2) Median

Explanation:

The Median of a series is the number in the center that represents the entire class of the series. Because it is a positional average, it is derived by observing a series rather than using the series' extreme values. As a result, the extreme values of a series have no effect on the median.

The median is only affected by the value of the middle point or points; it is unaffected by the values of the remaining points.
