 Standard Deviation Shows   Education Introduction to standard deviation shows: In statistics, the standard deviation shows about the statistical population, a data set, or a probability distribution is the square root of its variance. Standard deviation is a widely used measure of the variability or dispersion, being algebraically more tractable though practically less robust than average absolute deviation. A low standard deviation indicates that the data points tend to be very close to the mean, whereas high standard deviation indicates that the data spread over a large range of values. Standard Deviation Shows: Standard deviation shows that the variation for the given set of data’s. This Standard deviation shows the variation from population, a data set, and probability distribution etc… Formulas to which shows the standard deviation are, Mean: `barx` = `( sum(x) ) / n` Standard deviation: S =` sqrt(((sum(x - barx)^2)) / (n-1))` By using these formulas we can able to shows...
