    paragraph

Standard Deviation

31. Standard deviation is the square root of variance, showing dispersion in the same units as the data.
32. It’s a widely-used measure of spread because it’s in the same units as the original data.
33. A high standard deviation means data points are widely spread from the mean; low means they’re close.
