Standard deviation in alteryx

Webb10 maj 2024 · The formula for calculating the z-score of any particular data set is z = (x - μ) / σ where μ is the mean of a population and σ is the standard deviation of a population. The absolute value of z represents the z-score of the population, the distance between the raw score and population mean in units of standard deviation.

What does standard deviation say about your dataset? If all values in a dataset are equal (like Dataset B which is {3, 3, 3, 3, 3}), the standard deviation is 0. In other words, If the standard deviation is small, the values lie close to the mean. If the standard deviation is large, the values lie far away from the mean. 4.
