Definition
developed by Fischer, method used to compare processes or groups through contrasting means. Decomposes the variation of data into internal "within" groups, and "between" groups
Term
FMEA
Definition
Systemized group of activities designed to recognie and evaluate potential failure of a product, process that looks to maximize the probability of failure
Term
interaction
Definition
a dependence relationship between the response and levels of 2 or more variables (in 2 way anova)
Term
DOE
Definition
an experiment where 1 or more variables believed to have an effect on the outcome are identified and manipulated
Term
response variable
Definition
outcome variable being investigated (independent variable)
Term
primary variable
Definition
controlled variablebelieved most likely to have an effect on the response variable (independent variable)
Term
background variable
Definition
variables identified by the designer of the experiment which may have an effect but cannot or will not be deliberately manipulated or held constant
Term
replication
Definition
collection of more than 1 observation for the same set of data

a better and practical way to perform experiments, all factors involved have only 2 levels
Term
control
Definition
in this phase, it is vital to determine how to keep the x's at their optimum levels so Y will also be on target with minimum variation
