In hypothesis testing, an error incurred by rejecting a null hypothesis when it is actually true (also called a type I error).

In hypothesis testing, a region in the sample space of the test statistic such that if the test statistic falls within it, the null hypothesis cannot be rejected. This terminology is used because rejection of H0 is always a strong conclusion and acceptance of H0 is generally a weak conclusion

In statistical hypothesis testing, this is a hypothesis other than the one that is being tested. The alternative hypothesis contains feasible conditions, whereas the null hypothesis speciies conditions that are under test

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.

Sequences of independent trials with only two outcomes, generally called “success” and “failure,” in which the probability of success remains constant.

A discrete random variable that equals the number of successes in a ixed number of Bernoulli trials.

A tabular arrangement expressing the assignment of members of a data set according to two or more categories or classiication criteria

A probability distribution for a continuous random variable.

A linear function of treatment means with coeficients that total zero. A contrast is a summary of treatment means that is of interest in an experiment.

A control chart in which the point plotted at time t is the sum of the measured deviations from target for all statistics up to time t

See U chart

W. Edwards Deming (1900–1993) was a leader in the use of statistical quality control.

The amount of variability exhibited by data

Another name for a cumulative distribution function.

The error sum of squares divided by its number of degrees of freedom.

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.

A signal from a control chart when no assignable causes are present

A method of variable selection in regression, where variables are inserted one at a time into the model until no other variables that contribute signiicantly to the model can be found.

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

The harmonic mean of a set of data values is the reciprocal of the arithmetic mean of the reciprocals of the data values; that is, h n x i n i = ? ? ? ? ? = ? ? 1 1 1 1 g .
