A single number, such as 478912, always has a standard deviation of 0.
Standard deviation calculation is somewhat difficult.Please refer to the site below for more info
Standard deviations are measures of data distributions. Therefore, a single number cannot have meaningful standard deviation.
standard deviation is the square roots of variance, a measure of spread or variability of data . it is given by (variance)^1/2
Standard deviation is a measure of the spread of data.
The standard deviation is a measure of the spread of data.
No, if the standard deviation is small the data is less dispersed.
A standard deviation calculator allows the user to find the mean spread away from the mean in a statistical environment. Most users needing to find the standard deviation are in the statistics field. Usually, the data set will be given and must be typed into the calculator. The standard deviation calculator will then give the standard deviation of the data. In order to find the variance of the data, simply square the answer.
Standard deviation is a measure of variation from the mean of a data set. 1 standard deviation from the mean (which is usually + and - from mean) contains 68% of the data.
Standard deviation is the variance from the mean of the data.
No. Variance and standard deviation are dependent on, but calculated irrespective of the data. You do, of course, have to have some variation, otherwise, the variance and standard deviation will be zero.
