Find the z score corresponding to x 44
WebLet x represent the data value, mu represent the mean, sigma represent the standard deviation, and z represent the z-score. Since the z-score is the number of standard deviations above the mean, z = (x - mu)/sigma. Solving for the data value, x, gives the formula x = … WebHow do we find the Z score? First, convert the variance (σ 2) to standard deviation (σ) by taking its square root: σ = √90000 = 300. Then the solution is simply: z = (1600 - 1000) / 300 = 600 / 300 = 2 This tells us that the …

WebFeb 15, 2024 · The formula for calculating a z-score is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation. As the formula shows, the z-score is simply the raw score minus the population mean, divided by the population standard deviation. Figure 2. Z-score formula in a population.
