WEBSep 11, 2023 · To calculate standard deviation, start by calculating the mean, or average, of your data set. Then, subtract the mean from all of the numbers in your data set, and square each of the differences. Next, add all the squared numbers together, and divide the sum by n minus 1, where n equals how many numbers are in your data set. Views: 2.7M

WEBStep 1. Work out the mean. In the formula above μ (the greek letter "mu") is the mean of all our values ... Example: 9, 2, 5, 4, 12, 7, 8, 11, 9, 3, 7, 4, 12, 5, 4, 10, 9, 6, 9, 4. The mean is: 9+2+5+4+12+7+8+11+9+3+7+4+12+5+4+10+9+6+9+4 20. = 140 20 = 7. And so μ = 7. Step 2. Then for each number: subtract the Mean and square the result.

WEBThe standard deviation (SD) is a single number that summarizes the variability in a dataset. It represents the typical distance between each data point and the mean. Smaller values indicate that the data points cluster closer to the mean—the values in the dataset are relatively consistent.

WEBBy calculating standard deviation, you can find out whether the numbers are close to or far from the mean. If the data points are far from the mean, then there is a large deviation in the data set. Thus, the greater the scatter in the data, the higher the standard deviation.
