In mathematics and statistics, deviation serves as a measure to quantify the disparity between an observed value of a variable and another designated value

Standard deviation is a measure which shows how much variation (such as spread, dispersion, spread,) from the mean exists.

In general: how far from the normal. In statistics: the difference between a single value and the mean of all values in a set. Here we see some deviations:.

Mean deviation is a statistical measure that computes the average deviation from the average value of a given data collection. Learn the mean deviation ...

Mean deviation is used to compute how far the values in a data set are from the center point. Mean, median, and mode all form center points of the data set.

In statistics, the standard deviation is a measure of the amount of variation of the values of a variable about its mean.

The Standard Deviation is a measure of how spread out numbers are. Its symbol is σ (the greek letter sigma). The formula is easy: it is the square root of the ...

In statistics and mathematics, the deviation is a measure which is used to find the difference between the observed value and the expected value of a variable.

Data sets with a small standard deviation are tightly grouped around the mean, whereas a larger standard deviation indicates the data is more spread out.
