Z-Score Definition, Formula and Calculation Statistics

The formula for calculating a z-score is z=(x-μ)/σ, where μ is the population mean and σ is the population standard deviation (note if you don't know the population standard deviation or the sample size is below 6, you should use a t-score instead of a z-score). In other words, the formula is z = (data point mean) / standard deviation.
