WebZ-Score Formula. When calculating the z-score of a single data point x; the formula to calculate the z-score is the difference of the raw data score minus the population mean, divided by the population standard deviation. z = x − μ σ. z = standard score. x = raw observed data point. μ = population mean. σ = population standard deviation. WebZ-score from P-value. This online calculator calculates the z score from the p-value.
