Deviation (statistics) - Wikipedia
a set of deviations, such as the standard deviation and the mean absolute deviation, measures of dispersion, and the mean signed deviation, a measure
Percentage point - Wikipedia
for the standard deviation is confusing, since percentage is also used as a unit for the relative standard deviation, i.e. standard deviation divided
Unbiased estimation of standard deviation - Wikipedia
unbiased estimation of a standard deviation is the calculation from a statistical sample of an estimated value of the standard deviation (a measure of statistical
Student's t-test - Wikipedia
to t if s was the actual standard deviation of x, while it is the sample standard deviation as the actual standard deviation is not generally known. Therefore
Standard deviation - Wikipedia
A low standard deviation indicates that the values tend to be close to their average (also called the expected value or arithmetic mean) of the set, while a high standard deviation indicates that the …
Standard normal table - Wikipedia
distribution with mean μ and standard deviation σ, its Z-score may be calculated from X by subtracting μ and dividing by the standard deviation: Z = X − μ σ {\displaystyle
Coefficient of variation - Wikipedia
also known as normalized root-mean-square deviation (NRMSD), percent RMS, and relative standard deviation (RSD), is a standardized measure of dispersion
Standard score - Wikipedia
In statistics, the standard score or z-score is the number of standard deviations by which the value of a raw score (i.e., an observed value or data point)
Chebyshev's inequality - Wikipedia
is the standard deviation (the square root of the variance). The rule is often called Chebyshev's theorem, about the range of standard deviations around
Standard deviation - Wikipedia
to calculate standard error for a finite sample, and to determine statistical significance. When only a sample of data from a population is available,
Distance correlation - Wikipedia
used in its specification, specifically: distance variance, distance standard deviation, and distance covariance. These quantities take the same roles as

Reduced chi-squared statistic - Wikipedia
\chi _{\nu }^{2}} equals the sample variance, the squared sample standard deviation. As a general rule, when the variance of the measurement error is
R score - Wikipedia
uniform examination subjects in Secondary 4 and 5. The IDGZ is the standard deviation of the students' Zsec scores. The inclusion of the ISGZ and the IDGZ
Sharpe ratio - Wikipedia
returns of the investment and the risk-free return, divided by the standard deviation of the investment returns. It represents the additional amount of
Bessel's correction - Wikipedia
n − 1 instead of n in the formula for the sample variance and sample standard deviation, where n is the number of observations in a sample. This method corrects
