The … WebbThe standard deviation is a measure of how close the numbers are to the mean. If the standard deviation is big, then the data is more "dispersed" or "diverse". As an example …
WebbA standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

WebbThis value tells you the relative size of the standard deviation compared to the mean. Analysts often report the coefficient of variation as a percentage. In this example, the standard deviation is 25% the size of the mean. If the value equals one or 100%, the standard deviation equals the mean. income assistance texasWebb5 apr. 2024 · Standard deviation is a statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance.
