• Acceptance region

  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

• 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).

• Alias

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

• Analytic study

  A study in which a sample from a population is used to make inference to a future population. Stability needs to be assumed. See Enumerative study

• Attribute control chart

  Any control chart for a discrete random variable. See Variables control chart.

• Bayes’ theorem

  An equation for a conditional probability such as PA B ( | ) in terms of the reverse conditional probability PB A ( | ).

• Categorical data

  Data consisting of counts or observations that can be classiied into categories. The categories may be descriptive.

• 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.

• Chance cause

  The portion of the variability in a set of observations that is due to only random forces and which cannot be traced to speciic sources, such as operators, materials, or equipment. Also called a common cause.

• Chi-square (or chi-squared) random variable

  A continuous random variable that results from the sum of squares of independent standard normal random variables. It is a special case of a gamma random variable.

• Components of variance

  The individual components of the total variance that are attributable to speciic sources. This usually refers to the individual variance components arising from a random or mixed model analysis of variance.

• Correlation

  In the most general usage, a measure of the interdependence among data. The concept may include more than two variables. The term is most commonly used in a narrow sense to express the relationship between quantitative variables or ranks.

• Cumulative sum control chart (CUSUM)

  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

• Decision interval

  A parameter in a tabular CUSUM algorithm that is determined from a trade-off between false alarms and the detection of assignable causes.

• 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 uniform random variable

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

• Frequency distribution

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

• Geometric mean.

  The geometric mean of a set of n positive data values is the nth root of the product of the data values; that is, g x i n i n = ( ) = / w 1 1 .

• Hat matrix.

  In multiple regression, the matrix H XXX X = ( ) ? ? -1 . This a projection matrix that maps the vector of observed response values into a vector of itted values by yˆ = = X X X X y Hy ( ) ? ? ?1 .
