Human height tends to follow a normal distribution. For example, 80 percent of men are somewhere between 5 feet 4 inches tall and 6 feet tall, with the largest number of men standing 5 feet 8 inches tall. Smaller and taller heights are increasingly rare, as they become more extreme. For instance, less than 0.01% of the adult male population is greater than 7 feet tall or shorter than 3 feet tall.
