You can use the following formula to calculate the percentile of a normal distribution based on a mean and standard deviation: Percentile Value = μ + zσ where: μ: Mean z: z-score from z table that corresponds to percentile value σ: Standard deviation The following examples show how to use this formula in practice.CV percentage equation. To find the coefficient of variation as a percentage, simply multiply the result from the above equation by 100. E.g. with a mean of 5 and sigma of 3, CV = 0.6. To get the CV as a percentage, calculate 0.6 · 100 = 60%.To solve this, we can use the raw score formula: Raw score = μ + zσ; Raw score = 81+ (-2)*5; Raw score = 71; A student with a z-score of -2 received an exam score of 71. Example 3: Plant Heights. The mean height of a certain species of plant is 8 inches with a standard deviation of 1.2 inches. Suppose a certain plant has a height with a z ...

For example, to calculate the 75th percentile of exam scores for each class you can replace 0.9 with 0.75 in the formula. Additional Resources.
