Z score test statistic calculator

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.
