Webb21 sep. 2024 · For the first question, we simply plug x = 13 into our z -score formula. The result is: (13 – 10)/2 = 1.5. This means that 13 is one and a half standard deviations above the mean. The second question is similar. Simply plug x = 6 into our formula. The result for this is: (6 – 10)/2 = -2. The interpretation of this is that 6 is two standard ... WebbThe Z-Score Calculator uses the following formula: z = (x - μ) / σ. Where: z is the standard score or Z-score, x is the raw score to be standardized, μ is the mean of the population, σ is the standard deviation of the population. Z-Score Calculation Example.
