Unbiased estimator.

A distribution with two modes

The joint probability distribution of two random variables.

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

A second-order response surface design in k variables consisting of a two-level factorial, 2k axial runs, and one or more center points. The two-level factorial portion of a CCD can be a fractional factorial design when k is large. The CCD is the most widely used design for itting a second-order model.

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.

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.

The mean of the conditional probability distribution of a random variable.

The probability of an event given that the random experiment produces an outcome in another event.

An estimator that converges in probability to the true value of the estimated parameter as the sample size increases.

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

A correction factor used to improve the approximation to binomial probabilities from a normal distribution.

A continuous random variable with range of a inite interval and a constant probability density function.

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.

A quality tool that graphically shows the location of defects on a part or in a process.

A subset of a sample space.

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 model that contains only irstorder terms. For example, the irst-order response surface model in two variables is y xx = + ?? ? ? 0 11 2 2 + + . A irst-order model is also called a main effects model
