Proportion from mean and standard deviation

Webb5 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. The standard deviation is calculated as... WebbThe deviation from this assumed mean is calculated as d = x - A.
