The sample mean's standard error is the standard deviation of the set of means that would be found by drawing an infinite number of repeated samples from the population and computing a mean for each sample. The standard deviation of a population or sample and the standard error of a statistic (e.g., of the sample mean) are quite different, but related. A useful property of the standard deviation is that, unlike the variance, it is expressed in the same unit as the data. It is algebraically simpler, though in practice less robust, than the average absolute deviation. The standard deviation of a random variable, sample, statistical population, data set, or probability distribution is the square root of its variance. Standard deviation may be abbreviated SD, and is most commonly represented in mathematical texts and equations by the lower case Greek letter σ (sigma), for the population standard deviation, or the Latin letter s, for the sample standard deviation. A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range. In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. Its ease of use and accuracy make it an essential tool for anyone who needs to analyze data regularly.Cumulative probability of a normal distribution with expected value 0 and standard deviation 1 The new Standard Deviation Calculator ( ) from Calculator.io is the latest addition to the platform's extensive selection of online calculators.
