am is affected by very large and very small values,but median and mode not affected by them. explain

Median and mode are "positional averages" that are not based on all the items in series. The indicate the average value based on the position of the value on the series, irrespective of the values of the observation in the series. In this way, they are not affected by the presence of extreme values in the series. Arithmetic Mean, on the other hand, is based on the value of all the observations in the series, thereby, is highly affected by the presence of extreme values.
