A handful of extreme values can drag the average well away from where most of the data actually sits — the median, not the mean, is the more honest "typical value" for skewed distributions like income or home prices.
Averages are pulled toward outliers because every value contributes proportionally to the sum — the median only cares about rank order, which is exactly why it resists a few extreme values that would distort the mean.
The median is not automatically the honest one either. It ignores magnitude entirely, so it hides exactly the tail that matters in insurance losses or system latency — where the 99th percentile is the number with consequences and the median is the one that reassures.
Estimate with the rule, then check it against the calculator that models it properly.
