Key Statistics Terms and definitions covered in this textbook. All possible (subsets) regressionsA method of variable selection in regression that examines all possible subsets of the candidate regressor variables. Eficient computer algorithms have been developed for implementing all possible regressions. Analytic studyA 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. AttributeA qualitative characteristic of an item or unit, usually arising in quality control.

For example, classifying production units as defective or nondefective results in attributes data. Average run length, or ARLThe 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. Causal variableWhen y fx = ( ) and y is considered to be caused by x, x is sometimes called a causal variable. Cause-and-effect diagramA chart used to organize the various potential causes of a problem. Also called a ishbone diagram. Central limit theoremThe simplest form of the central limit theorem states that the sum of n independently distributed random variables will tend to be normally distributed as n becomes large. It is a necessary and suficient condition that none of the variances of the individual random variables are large in comparison to their sum.

There are more general forms of the central theorem that allow ininite variances and correlated random variables, and there is a multivariate version of the theorem. Central tendencyThe 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 causeThe 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. Comparative experimentAn experiment in which the treatments (experimental conditions) that are to be studied are included in the experiment.

Travie mccoy songs. The data from the experiment are used to evaluate the treatments. Conidence levelAnother term for the conidence coeficient.

Counting techniquesFormulas used to determine the number of elements in sample spaces and events. Defects-per-unit control chartSee U chart. Deining relationA subset of effects in a fractional factorial design that deine the aliases in the design. Design matrixA matrix that provides the tests that are to be conducted in an experiment. Designed experimentAn experiment in which the tests are planned in advance and the plans usually incorporate statistical models. See Experiment. DispersionThe amount of variability exhibited by data.

Factorial experimentA type of experimental design in which every level of one factor is tested in combination with every level of another factor. In general, in a factorial experiment, all possible combinations of factor levels are tested. Fraction defective control chartSee P chart. Gaussian distributionAnother 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.
