Standard deviation - Wikipedia
Web13 mrt. 2024 · Divide the average deviation by the mean, then multiply by 100. The number you get will show the average percentage that a data point differs from the mean. Your melons have a mean weight of 5 pounds, and an average deviation of 1.5 pounds, so: percent deviation = 1.5 / 5 x 100 = 30 percent Web7 sep. 2024 · To compute the mean you can avoid the building of the list of values by using np.average which takes a weights argument: vals, freqs = np.array (freqdist).T np.average (vals, weights = freqs) gives 20.6 as you would expect. I don't think this works for the mean, variance, or standard deviation, though.
