"Average person eats 3 spiders a year" factoid statistically correct but misleading. Median person eats 0 spiders per year. Spiders Georg, who lives in cave & eats over 10,000 each day, is an outlier adn should be included in the average for completeness, but serves as an example of why medians are often more representative of a population.
"Average person eats 3 spiders a year" factoid statistically correct for definition of "average" = "statistical mean." Median person (and modal persons), which are also often colloquially referred to as "average," eats 0 spiders per year. Spiders Georg, who lives in cave & eats over 10,000 each day, is an outlier adn may or may not be included in the mean, depending on the nature of the study and the intention of the authors, but should probably be noted specifically regardless, and further study may be necessary to determine the cause of the anomaly.
