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.
The utilization of the between-group experimental design has several advantages. First, multiple variables, or multiple levels of a variable, can be tested simultaneously, and with enough testing subjects, a large number can be tested. Thus, the inquiry is broadened and extended beyond the effect of one variable (as with within-subject design).
Experimental psychology refers to work done by those who apply experimental methods to psychological study and the underlying processes. Experimental psychologists employ human participants and animal subjects to study a great many topics, including (among others) sensation, perception, memory, cognition, learning, motivation, emotion; developmental processes, social psychology, and the neural ...
Experiment, often with separate treatment and control groups (see scientific control and design of experiments). See Experimental psychology for many details. Field experiment; Focus group; Interview, can be structured or unstructured. Meta-analysis; Neuroimaging and other psychophysiological methods
A clinical control group can be a placebo arm or it can involve an old method used to address a clinical outcome when testing a new idea. For example in a study released by the British Medical Journal, in 1995 studying the effects of strict blood pressure control versus more relaxed blood pressure control in diabetic patients, the clinical control group was the diabetic patients that did not ...
Given the basic design, the hypothesis and the particular conditions for the experiment, an experimental paradigm must be made up. The paradigm typically includes factors such as experimental instructions for the subjects, the physical design of the experiment room, and the rules for process of the trial or trials to be carried out.

Students in psychology need to learn to design and analyze their own experiments. However, software that allows students to build experiments on their own has been limited in a variety of ways. E-Prime is the standard for building experiments in psychology, STEP is a Web-based resource that uses E-Prime as the delivery engine for a wide variety ...
In design of experiments, single-subject curriculum or single-case research design is a research design most often used in applied fields of psychology, education, and human behaviour in which the subject serves as his/her own control, rather than using another individual/group. Researchers use single-subject design because these designs are ...
