-
`-error (or `-risk)
In hypothesis testing, an error incurred by rejecting a null hypothesis when it is actually true (also called a type I error).
-
a-error (or a-risk)
In hypothesis testing, an error incurred by failing to reject a null hypothesis when it is actually false (also called a type II error).
-
Addition rule
A formula used to determine the probability of the union of two (or more) events from the probabilities of the events and their intersection(s).
-
Average run length, or ARL
The average number of samples taken in a process monitoring or inspection scheme until the scheme signals that the process is operating at a level different from the level in which it began.
-
Chi-square test
Any test of signiicance based on the chi-square distribution. The most common chi-square tests are (1) testing hypotheses about the variance or standard deviation of a normal distribution and (2) testing goodness of it of a theoretical distribution to sample data
-
Conditional mean
The mean of the conditional probability distribution of a random variable.
-
Conidence level
Another term for the conidence coeficient.
-
Continuous random variable.
A random variable with an interval (either inite or ininite) of real numbers for its range.
-
Critical value(s)
The value of a statistic corresponding to a stated signiicance level as determined from the sampling distribution. For example, if PZ z PZ ( )( .) . ? =? = 0 025 . 1 96 0 025, then z0 025 . = 1 9. 6 is the critical value of z at the 0.025 level of signiicance. Crossed factors. Another name for factors that are arranged in a factorial experiment.
-
Cumulative distribution function
For a random variable X, the function of X deined as PX x ( ) ? that is used to specify the probability distribution.
-
Deming
W. Edwards Deming (1900–1993) was a leader in the use of statistical quality control.
-
Deming’s 14 points.
A management philosophy promoted by W. Edwards Deming that emphasizes the importance of change and quality
-
Discrete random variable
A random variable with a inite (or countably ininite) range.
-
Enumerative study
A study in which a sample from a population is used to make inference to the population. See Analytic study
-
Error of estimation
The difference between an estimated value and the true value.
-
Error variance
The variance of an error term or component in a model.
-
F distribution.
The distribution of the random variable deined as the ratio of two independent chi-square random variables, each divided by its number of degrees of freedom.
-
Frequency distribution
An arrangement of the frequencies of observations in a sample or population according to the values that the observations take on
-
Gamma random variable
A random variable that generalizes an Erlang random variable to noninteger values of the parameter r
-
Gaussian distribution
Another name for the normal distribution, based on the strong connection of Karl F. Gauss to the normal distribution; often used in physics and electrical engineering applications
