Flashcards: Design of experiments

An institutional review board (IRB), also known as an independent ethics committee (IEC), ethical review board (ERB), or research ethics board (REB), is a type of committee used in research in the United States that has been formally designated to approve, monitor, and review biomedical and behavioral research involving humans.

In statistics, response surface methodology (RSM) explores the relationships between several explanatory variables and one or more response variables.

In randomized statistical experiments, generalized randomized block designs (GRBDs) are used to study the interaction between blocks and treatments.

Orthogonal array testing is a black box testing technique that is a systematic, statistical way of software testing.

In mathematical statistics, the Fisher information (sometimes simply called information) is a way of measuring the amount of information that an observable random variable X carries about an unknown parameter θ of a distribution that models X.

A blind — or blinded — experiment is an experiment in which information about the test is masked (kept) from the participant, to reduce or eliminate bias, until after a trial outcome is known.

In statistical hypothesis testing, a type I error is the incorrect rejection of a true null hypothesis (a "false positive"), while a type II error is incorrectly retaining a false null hypothesis (a "false negative").

In the design of experiments, optimal designs (or optimum designs) are a class of experimental designs that are optimal with respect to some statistical criterion.

Drug design, often referred to as rational drug design or simply rational design, is the inventive process of finding new medications based on the knowledge of a biological target.

Repeated measures design uses the same subjects with every branch of research, including the control.

A longitudinal survey is a correlational research study that involves repeated observations of the same variables over long periods of time, often many decades; basically, an empirical study of people with a common characteristic.

Matching is a statistical technique which is used to evaluate the effect of a treatment by comparing the treated and the non-treated units in an observational study or quasi-experiment (i.e. when the treatment is not randomly assigned).
