Z Score Calculator. This simple calculator allows you to calculate a standardized z -score for any raw value of X. Just enter your raw score, population mean and standard deviation, and hit
The z-score can be calculated by subtracting the population mean from the raw score, or data point in question (a test score, height, age, etc.), then dividing the difference by the population standard deviation: z = x - μ σ where x is the raw score, μ is the population mean, and σ is the population standard deviation.

How to Convert Z-Scores to Raw Scores (Step-by-Step)
The algorithm behind this Z Score calculator uses the formula explained here: Z Score = (x- µ)/ σ. Where: x = raw score value; µ = population mean; σ = population standard deviation. Example
