Factorial experiment — In statistics, a factorial experiment is an experiment whose design consists of two or more factors, each with discrete possible values or levels , and whose experimental units take on all possible combinations of these levels across all such… … Wikipedia
Effect size — In statistics, an effect size is a measure of the strength of the relationship between two variables in a statistical population, or a sample based estimate of that quantity. An effect size calculated from data is a descriptive statistic that… … Wikipedia
factorial table — noun a) A tabular presentation of data used to show the influence of two independent categorical variables on a dependent variable. b) An arrangement of data showing the effect of more than two categorical variables on a dependent variables … Wiktionary
Fractional factorial design — In statistics, fractional factorial designs are experimental designs consisting of a carefully chosen subset (fraction) of the experimental runs of a full factorial design. The subset is chosen so as to exploit the sparsity of effects principle… … Wikipedia
Main effect — In the design of experiments and analysis of variance, a main effect is the effect of an independent variable on a dependent variable averaging across the levels of any other independent variables. The term is frequently used in the context of… … Wikipedia
Memoization — Not to be confused with Memorization. In computing, memoization is an optimization technique used primarily to speed up computer programs by having function calls avoid repeating the calculation of results for previously processed inputs.… … Wikipedia
Yates analysis — Full and fractional factorial designs are common in designed experiments for engineering and scientific applications. In these designs, each factor is assigned two levels. These are typically called the low and high levels. For computational… … Wikipedia

Restricted randomization — Many processes have more than one source of variation in them. In order to reduce variation in processes, these multiple sources must be understood, and that often leads to the concept of nested or hierarchical data structures. For example, in… … Wikipedia
Analysis of variance — In statistics, analysis of variance (ANOVA) is a collection of statistical models, and their associated procedures, in which the observed variance in a particular variable is partitioned into components attributable to different sources of… … Wikipedia
