Design and analysis of experiments notes

How do you set up a DOE?
The experimental design is a set of procedures that are designed to test a hypothesis.
The process has five steps: define variables, formulate a hypothesis, design an experiment, assign subjects, and measure the dependent variable..
Principles of experiment design
When to use DOE? To determine whether a factor, or a collection of factors, has an effect on the response.
To determine whether factors interact in their effect on the response.
To model the behavior of the response as a function of the factors..
What are the principles of DOE?
Programs that do not pay attention to this key principle of design of experiments (DOE) (the key principles being 1) randomization, 2) replication, and 3) local control or blocking) run unknown risks associated with not adequately understanding the importance of assumptions within statistical tests and methods..
What is the purpose of a DOE?
When to use DOE? To determine whether a factor, or a collection of factors, has an effect on the response.
To determine whether factors interact in their effect on the response.
To model the behavior of the response as a function of the factors..

Planning an experiment to obtain appropriate data and drawing inference out of the data with respect to any problem under investigation is known as design and

What are the characteristics of a good experimental design?

The design should be as simple as possible, consistent with the objectives of the experiment

Absence of systematic error

Experimental units receiving one treatment should not differ in any systematic way from those receiving another treatment so that an unbiased estimate of each treatment effect can be obtained

Range of validity of conclusions
