Finding standard deviation from variance
WebHere's how to calculate population standard deviation: Step 1: Calculate the mean of the data—this is \mu μ in the formula. Step 2: Subtract the mean from each data point. … WebSay we have a bunch of numbers like 9, 2, 5, 4, 12, 7, 8, 11. To 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.
