Measuring the amount of body fat a person carries is one way to monitor weight control progress, but measuring it accurately involves either expensive X-ray equipment or a pool in which to dunk the subject. Instead body mass index (BMI) is often used as a proxy for body fat because it is easy to measure: BMI = mass(kg)/(height(m))² = 703 mass(lb)/(height(in))². In a study of 15 men at TXST, both BMI and body fat were measured. Researchers imported the data into statistical software for analysis. A few values are missing from the output.
