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.

Oct 04, 2019 · z = (X – μ) / σ Where, X is the value of the element μ is the population mean σ is the standard deviation Let’s solve an example. For instance, let’s say you have a test score of 85. If the test has a mean (μ) of 45 and a standard deviation (σ) of 23, what’s your z score? X = 85, μ = 45, σ = 23 z = (85 – 45) / 23 = 40 / 23 z = 1.7391

Find the z-score probability of 63? Solution: Given scores, 63, 87,47. Find the mean and standard deviation of the scores. μ = (67+87+47)/3 = 67. σ = √ ( (67-67)^2 + (87-67)^2 + (47-67)^2)/3= 28.284 Here, x = 63. Now, apply the formula, z = (x - μ) / σ z = (63 - 67)/28.284 = -4/28.28 = -0.14.
