In statistics, the range is a measure of the total spread of values in a quantitative dataset. Unlike other more popular measures of dispersion, the range actually measures total dispersion (between the smallest and largest values) rather than relative dispersion around a measure of central tendency.

A low standard deviation means that the data is very closely related to the average, thus very reliable. Standard deviation (SD) is a widely used measurement of variability used in statistics. It shows how much variation there is from the average (mean). A low SD indicates that the data points tend to be close to the mean, whereas a high SD indicates that the data are spread out over a large range of values. Standard deviation.

## Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean or expected value).A low standard deviation means that most of the numbers are close to the average, while a high standard deviation means that the numbers are more spread out.

Standard Deviation. A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out. Standard deviation (SD) is a widely used measurement of variability used in statistics.

The salaries are generally distributed with the population mean of µ = $60,000, and the population standard deviation σ = $15000. However, in statistics, we are usually presented with a sample from which we wish to estimate (generalize to) a population, and the standard deviation is no exception to this. Therefore, if all you have is a sample, but you wish to make a statement about the population standard deviation from which the sample is drawn, you need to use the sample standard deviation. In statistics, standardization is the process of putting different variables on the same scale.
