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

WEBSep 17, 2020 · The standard deviation is the average amount of variability in your dataset. It tells you, on average, how far each value lies from the mean. A high standard deviation means that values are generally far from the mean, while a low standard deviation indicates that values are clustered close to the mean.

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.
