The amount that remains after one quantity is subtracted from another. Deviation (Statistics) The difference, especially the absolute difference, between one number in a set of data and the mean of that set of data. Difference To distinguish or differentiate. Deviation The act of deviating; wande...
What is the difference in the means as a multiple of the mean absolute deviations? What does it mean if the standard deviation is close to the mean? Given the following data 0.05, 0.23, 0.35, 0.14, 0.13, 0.10 . What is the mean, variance, standard deviation, and expected...

In statistical terms, deviation is quantitatively measured, such as the difference between an observed value and the mean of a dataset. Variation, while it can also be measured, is more broadly used to describe the overall dispersion or spread of a dataset, like the variance or standard deviati...

Suppose a 95% confidence interval for a population mean has been calculated, and it extends from 123.7 to 155.2. Some people would then state, [{MathJax fullWidth='false' `` }]The probability that the population mean is between 123.7 and 155.2 is 0.95." W ...
, the altitude on the hypotenuse is equal to the geometric mean of line segments formed by altitude on the hypotenuse. for a right triangle, when a perpendicular is drawn from the vertex to the hypotenuse, two similar right triangles are formed. this is called the right triangle altitude ...
For general Wigner-type matrices (in which the matrix entries are not normalised to have mean zero), we can use the inverse Littlewood-Offord theorem of Nguyen and Vu to obtain (under mild conditions on ) a result of the form for any and , if is sufficiently large depending on (in a...
Why do we use the standard deviation as a measure of the uncertainty in single timing measurements rather than the rounding uncertainty on the timers themselves? Why do we use the standard uncertainty in the mean to quantify the uncertainty in the mean of a data set, but we use the...
