Webb8 jan. 2024 · We can use the following steps to calculate the z-score: The mean is μ = 80. The standard deviation is σ = 4. The individual value we’re interested in is X = 75. Thus, z = (X – μ) / σ = (75 – 80) /4 = –1.25. This tells us that an exam score of 75 lies 1.25 standard deviations below the mean. WebbIncludes: Standard deviations, cumulative percentages, percentile equivalents, Z-scores, T-scores.
