WebA z-score measures exactly how many standard deviations above or below the mean a data point is. Here's the formula for calculating a z-score: z=\dfrac {\text {data point}-\text {mean}} {\text {standard deviation}} z = standard deviationdata point − mean.

How to Calculate a Z-Score Using Microsoft Excel - How-To Geek
WebZ.TEST represents the probability that the sample mean would be greater than the observed value AVERAGE (array), when the underlying population mean is μ0. From the symmetry of the Normal distribution, if AVERAGE (array) < x, Z.TEST will return a value greater than 0.5. The following Excel formula can be used to calculate the two-tailed ... WebJul 18, 2024 · The equation below is the Z-score equation. By itself, the Z-score doesn't provide much information to you. It gains the most value when compared against a Z-table, which tabulates the cumulative probability of a standard normal distribution up until a given Z-score.
