• Alias

  In a fractional factorial experiment when certain factor effects cannot be estimated uniquely, they are said to be aliased.

• Asymptotic relative eficiency (ARE)

  Used to compare hypothesis tests. The ARE of one test relative to another is the limiting ratio of the sample sizes necessary to obtain identical error probabilities for the two procedures.

• 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.

• Axioms of probability

  A set of rules that probabilities deined on a sample space must follow. See Probability

• Cause-and-effect diagram

  A chart used to organize the various potential causes of a problem. Also called a ishbone diagram.

• Central tendency

  The tendency of data to cluster around some value. Central tendency is usually expressed by a measure of location such as the mean, median, or mode.

• Combination.

  A subset selected without replacement from a set used to determine the number of outcomes in events and sample spaces.

• Control chart

  A graphical display used to monitor a process. It usually consists of a horizontal center line corresponding to the in-control value of the parameter that is being monitored and lower and upper control limits. The control limits are determined by statistical criteria and are not arbitrary, nor are they related to speciication limits. If sample points fall within the control limits, the process is said to be in-control, or free from assignable causes. Points beyond the control limits indicate an out-of-control process; that is, assignable causes are likely present. This signals the need to ind and remove the assignable causes.

• Correction factor

  A term used for the quantity ( / )( ) 1 1 2 n xi i n ? = that is subtracted from xi i n 2 ? =1 to give the corrected sum of squares deined as (/ ) ( ) 1 1 2 n xx i x i n ? = i ? . The correction factor can also be written as nx 2 .

• 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.

• Defect

  Used in statistical quality control, a defect is a particular type of nonconformance to speciications or requirements. Sometimes defects are classiied into types, such as appearance defects and functional defects.

• Deming’s 14 points.

  A management philosophy promoted by W. Edwards Deming that emphasizes the importance of change and quality

• Design matrix

  A matrix that provides the tests that are to be conducted in an experiment.

• Discrete uniform random variable

  A discrete random variable with a inite range and constant probability mass function.

• Distribution free method(s)

  Any method of inference (hypothesis testing or conidence interval construction) that does not depend on the form of the underlying distribution of the observations. Sometimes called nonparametric method(s).

• Distribution function

  Another name for a cumulative distribution function.

• Finite population correction factor

  A term in the formula for the variance of a hypergeometric random variable.

• Fractional factorial experiment

  A type of factorial experiment in which not all possible treatment combinations are run. This is usually done to reduce the size of an experiment with several factors.

• Frequency distribution

  An arrangement of the frequencies of observations in a sample or population according to the values that the observations take on

• Goodness of fit

  In general, the agreement of a set of observed values and a set of theoretical values that depend on some hypothesis. The term is often used in itting a theoretical distribution to a set of observations.
