WebbIn statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values.A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range.
Webb21 apr. 2024 · A confidence interval for a population standard deviation is a range of values that is likely to contain a population standard deviation with a certain level of confidence. The formula to calculate this confidence interval is: Confidence interval = [√ (n-1)s 2 /X 2α/2, √ (n-1)s 2 /X 21-α/2] where: n: sample size. s 2: sample variance.
