Here, standard deviation is a measure of how spread out human height is. A larger standard deviation means a greater variation in height. The standard deviation automatically set in the height percentile calculator is approximated from Centers for Disease Control and World Health Organization data [1,2,3]. The wikipedia article on human height reports mean height for many different countries by sex but it does not report standard deviations.. What is the standard deviation of adult human heights within sexes? Obviously the size of the standard deviation would vary across countries and by other factors.
Each time height increases by 3", by a standard deviation, the population drops off considerably. There are just about exactly 100,000,000 adult men in America. Now that we know their average height is 5'10" and the standard deviation is 3", we can predict how many Founded: Feb 02, 1985. For example, adult male heights are on average 70 inches (5'10) with a standard deviation of 4 inches. Adult women are on average a bit shorter and less variable in height with a mean height of 65 inches (5'5) and standard deviation of 3.5 inches.
Each time height increases by 3", by a standard deviation, the population drops off considerably. There are just about exactly 100,000,000 adult men in America. Now that we know their average height is 5'9" and the standard deviation is 3", we can predict how many . If the standard deviation were zero, then all men would be exactly 70 inches (177.8 cm) tall. If the standard deviation were 20 inches (50.8 cm), then men would have much more variable heights, with a typical range of about 50–90 inches (127–228.6 cm).

From gender, age, height and bone age, it predicts the adult height. Optionally, one can enter parental height, which improves the accuracy. The uncertainties of the predictions of adult height are given as a standard deviation (±SD), i.e. the true values will be within the indicated range with 68% probability.
