what is two level factorial design The simplest factorial design involves two factors each at two levels The top part of Figure 3 1 shows the layout of this two by two design which forms the square X space on the left The equivalent one factor at a time OFAT experiment is shown at the upper right
The 2 k refers to designs with k factors where each factor has just two levels These designs are created to explore a large number of factors with each factor having the minimal number of levels just two Two level full factorial designs Description Graphical representation of a two level design with 3 factors Consider the two level full factorial design for three factors namely the 2 3 design This implies eight runs not counting replications or center point runs

This particular design is referred to as a 2 2 read two by two factorial design because it combines two variables each of which has two levels If one of the independent variables had a third level e g using a handheld cell phone using a hands free cell phone and not using a cell phone then it would be a 3 2 factorial In the example there were two factors and two levels which gave a 2 2 factorial design The Yates Algorithm can be used in order to quantitatively determine which factor affects the percentage of seizures the most
A factorial design is a type of experiment that involves manipulating two or more variables While simple psychology experiments look at how one independent variable affects one dependent variable researchers often want to know more about the effects of multiple independent variables Two level factorial experiments in which all combinations of multiple factor levels are used efficiently estimate factor effects and detect interactions desirable statistical qualities

Factorial experiments are described by two things the number of factors and the number of levels of each factor For example a 2 3 factorial experiment has two factors the first at 2 levels and the second at 3 levels Such an experiment has 2 3 6 treatment combinations or cells The two level factorial design tasks include DoE project goal setting in identify ing single or multiple output variables outcomes and how to measure and classify them
A 2k factorial design is a k factor design such that i Each factor has two levels coded 1 and 1 ii The 2 k experimental runs are based on the 2 combinations of the 1 factor levels What is a 2 level full factorial design In a 2 level full factorial design each experimental factor has only two levels The experimental runs include all combinations of these factor levels
