Find mean when standard deviation is given
WebTo calculate the standard deviation of those numbers: 1. Work out the Mean (the simple average of the numbers) 2. Then for each number: subtract the Mean and square the result 3. Then work out the mean of those squared differences. 4. Take the square root of that and we are done! The formula actually says all of that, and I will show you how. WebDec 24, 2024 · 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.
