Webb17 dec. 2013 · NORMSINV (mentioned in a comment) is the inverse of the CDF of the standard normal distribution. Using scipy, you can compute this with the ppf method of the scipy.stats.norm object. The acronym ppf stands for percent point function, which is another name for the quantile function..

A z-score simply tells you how many standard deviations away an individual data value falls from the mean. It is calculated as: z-score = (x – μ) / σ where: x: individual data value μ: population mean
