statistics, the standard deviation is a measure of the amount of variation of the values of a variable about its mean. A low standard deviation indicates that the...

deviation of a random variable (with finite variance) from its mean. More specifically, the probability that a random variable deviates from its mean...

and the standard deviation (the first L-moment and first conventional moment are both the mean). Both the standard deviation and the mean absolute difference...

related to the mean squared error, the equivalent for mean absolute error is least absolute deviations. MAE is not identical to root-mean square error (RMSE)...

sign of the data set. Which of these measures is most illuminating depends on what is being measured, and on context and purpose. The arithmetic mean...

number of standard deviations by which the value of a raw score (i.e., an observed value or data point) is above or below the mean value of what is being...

In electrocardiography, left axis deviation (LAD) is a condition wherein the mean electrical axis of ventricular contraction of the heart lies in a frontal...

observation is the deviation of the observed value from the true value of a quantity of interest (for example, a population mean). The residual is the...

variance is the expected value of the squared deviation from the mean of a random variable. The standard deviation (SD) is obtained as the square root of the...
