Z - score calculator

google play badge app store badge

This calculator solves three types of problems related to z-scores. 1. Find the area (probability) to the left, right, or between two Z-scores. 2. Find the z-score if the cumulative probability level (p-value) is given. 3. Find the z-score based on the raw value, mean and standard deviation of a population.

The calculator will generate a step-by-step explanation along with a graphic representation of the solution.
