Question

Which average is affected most by the presence of extreme items? 1

(I) Median (II) Mode (III) Arithmetic mean (IV) None of these​

Answer 1

Answer:

Arithmetic mean is affected most by extreme items

Explanation:

Median is that value that lies in the middle of a frequency distribution. Mode is the most-frequently occurring observation. Both these are not much affected by extreme values. However, arithmetic mean takes into account ALL observations and hence is most affected by extreme values.
