Standard Deviation By default numpy std returns the population standard deviation in which case np std 0 1 is correctly reported to be 0 5 If you are looking for the sample standard deviation you can supply an optional
Because now we know how likely the value of b i takes on we can measure the variability of b i given the collection by calculating the standard deviation of b i difference between each b i and the mean Compute the Z score based on the standard normal distribution represented by NormalDist for the given confidence using the inverse of the cumulative distribution function
