  2. Matching law - Wikipedia

    en.wikipedia.org/wiki/Matching_law

    When human participants perform under concurrent schedules of reinforcement, matching has been observed in some experiments, [8] but wide deviations from matching have been found in others. [9] Finally, if nothing else, the matching law is important because it has generated a great deal of research that has widened our understanding of operant ...

  3. Matching (statistics) - Wikipedia

    en.wikipedia.org/wiki/Matching_(statistics)

    Matching is a statistical technique that evaluates 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).

  4. Research design - Wikipedia

    en.wikipedia.org/wiki/Research_design

    A research design typically outlines the theories and models underlying a project; the research question(s) of a project; a strategy for gathering data and information; and a strategy for producing answers from the data. [1] A strong research design yields valid answers to research questions while weak designs yield unreliable, imprecise or ...

  5. Melioration theory - Wikipedia

    en.wikipedia.org/wiki/Melioration_theory

    Melioration theory in behavioral psychology is a theoretical algorithm that predicts the matching law. [1] Melioration theory is used as an explanation for why an organism makes choices based on the rewards or reinforcers it receives. The principle of melioration states that animals will invest increasing amounts of time and/or effort into ...

    Scientific method, a body of techniques for investigating phenomena, based on empirical or measurable evidence that is subject to the principles of logic and reasoning Observational study , draws inferences about the possible effect of a treatment on subjects, where the assignment of subjects into a treated group versus a control group is ...

  7. Realization (probability) - Wikipedia

    en.wikipedia.org/wiki/Realization_(probability)

    [2] [a] If an element in Ω is mapped to an element in state space by X, then that element in state space is a realization. Elements of the sample space can be thought of as all the different possibilities that could happen; while a realization (an element of the state space) can be thought of as the value X attains when one of the ...

  8. Single-subject research - Wikipedia

    en.wikipedia.org/wiki/Single-subject_research

    The reversal design is the most powerful of the single-subject research designs showing a strong reversal from baseline ("A") to treatment ("B") and back again. If the variable returns to baseline measure without a treatment then resumes its effects when reapplied, the researcher can have greater confidence in the efficacy of that treatment.

  9. Research proposal - Wikipedia

    en.wikipedia.org/wiki/Research_proposal

    A research proposal is a document proposing a research project, generally in the sciences or academia, and generally constitutes a request for sponsorship of that research. [1] Proposals are evaluated on the cost and potential impact of the proposed research, and on the soundness of the proposed plan for carrying it out. [ 2 ]
