- Standard deviation - Math.netStandard deviation is a statistical measure of variability that indicates the average amount that a set of numbers deviates from their mean. The higher the standard deviation, the more spread out the values, while a lower standard deviation indicates that the values tend to be close to the mean.
- 2.4: Standard Deviation – Intro to Statistics MAT1260The idea behind the standard deviation is to quantify the spread of a distribution by measuring how far the observations are from their mean, [latex]\bar{x}[/latex]. The standard deviation gives the average (or typical distance) between a data point and the mean, [latex]\bar{x}[/latex].
- Standard Deviation: Interpretations and CalculationsThe 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.
