  2. Factorial experiment - Wikipedia

    en.wikipedia.org/wiki/Factorial_experiment

    Designed experiments with full factorial design (left), response surface with second-degree polynomial (right) In statistics, a full 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 factors.

  3. Between-group design experiment - Wikipedia

    en.wikipedia.org/wiki/Between-group_design...

    A way to design psychological experiments using both designs exists and is sometimes known as "mixed factorial design". [3] In this design setup, there are multiple variables, some classified as within-subject variables, and some classified as between-group variables. [3] One example study combined both variables.

    Andy Field (2009) [1] provided an example of a mixed-design ANOVA in which he wants to investigate whether personality or attractiveness is the most important quality for individuals seeking a partner. In his example, there is a speed dating event set up in which there are two sets of what he terms "stooge dates": a set of males and a set of ...

    en.wikipedia.org/wiki/Design_of_experiments

    Design of experiments with full factorial design (left), response surface with second-degree polynomial (right) The design of experiments , also known as experiment design or experimental design , is the design of any task that aims to describe and explain the variation of information under conditions that are hypothesized to reflect the variation.

  6. Dynamic causal modeling - Wikipedia

    en.wikipedia.org/wiki/Dynamic_causal_modeling

    To enable efficient estimation of driving and modulatory effects, a 2x2 factorial experimental design is often used - with one factor serving as the driving input and the other as the modulatory input. [2] Resting state experiments have no experimental manipulations within the period of the neuroimaging recording.

  7. Multifactor design of experiments software - Wikipedia

    en.wikipedia.org/wiki/Multifactor_Design_of...

    Factorial experimental design software drastically simplifies previously laborious hand calculations needed before the use of computers. During World War II, a more sophisticated form of DOE, called factorial design, became a big weapon for speeding up industrial development for the Allied forces. These designs can be quite compact, involving a

    In such a case, the design is also said to be orthogonal, allowing to fully distinguish the effects of both factors. We hence can write ∀ i , j n i j = K {\displaystyle \forall i,j\;n_{ij}=K} , and ∀ i , j n i j = n i + ⋅ n + j n {\displaystyle \forall i,j\;n_{ij}={\frac {n_{i+}\cdot n_{+j}}{n}}} .

  9. Response surface methodology - Wikipedia

    en.wikipedia.org/wiki/Response_surface_methodology

    An easy way to estimate a first-degree polynomial model is to use a factorial experiment or a fractional factorial design.This is sufficient to determine which explanatory variables affect the response variable(s) of interest.
