Question

What is one main advantage of using the median instead of the mean in a dataset with extreme values?

Options

• The median always ignores the lowest value

• The median gives a better idea of centre when there are outliers

• The median increases the effect of outliers

• The median and mean are always equal

Answer 1

The median gives a better idea of centre when there are outliers.

Explanation:

The median is not greatly affected by extreme values, so it better represents the middle of skewed or outlier-heavy data.
