One single observation can disproportionately impact the aggregate. ![]() Bill Gates’s net worth is a million times more than that. The average net worth of an American household is ~100,000.

A single sample of 8 ft where the average is 6 ft can skew the overall ratio by only 0.08 ft (1 inch). ![]() The tallest human is about 8 ft tall the shortest is about 2 ft.
