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.

The calculator allows area look up with out the use of tables or charts. In addition it provide a graph of the curve with shaded and filled area. The z-score is the number of standard deviations from the mean. The standard normal distribution is a normal distribution with a standard deviation on 1 and a mean of 0. Instructions: Select area type.
