Statistics geeks rejoiced when the New York Times published an article on the normal curve (Dunn, 2013)! Biologist Casey Dunn wrote that “Many real-world observations can be approximated by, and tested against, the same expected pattern: the normal distribution.” He described the normal curve as symmetric and bell-shaped with more observations gathered near the mean. He offered several examples: “The size of flowers, the physiological response to a drug, the breaking force in a batch of steel cables,” but also noted that there are important exceptions, including household income. In your own words, explain to someone who has never taken statistics why household income, unlike Dunn’s other examples, is not normally distributed.
