  2. Quasi-experiment - Wikipedia

    en.wikipedia.org/wiki/Quasi-experiment

    A quasi-experiment is an empirical study used to estimate the causal impact of an intervention. Quasi-experiments shares similarities with experiments or randomized controlled trials, but specifically lack random assignment to treatment or control. Instead, quasi-experimental designs typically allow assignment to treatment condition to proceed ...

    The study of the design of experiments is an important topic in metascience. History ... a quasi-experimental design may be used. Causal attributions

  4. 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).

  5. Interrupted time series - Wikipedia

    en.wikipedia.org/wiki/Interrupted_time_series

    Interrupted time series design is the design of experiments based on the interrupted time series approach. The method is used in various areas of research, such as: political science: impact of changes in laws on the behavior of people; [2] (e.g., Effectiveness of sex offender registration policies in the United States)

  6. Regression discontinuity design - Wikipedia

    In statistics, econometrics, political science, epidemiology, and related disciplines, a regression discontinuity design (RDD) is a quasi-experimental pretest–posttest design that aims to determine the causal effects of interventions by assigning a cutoff or threshold above or below which an intervention is assigned.

  7. Blocking (statistics) - Wikipedia

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

    In the statistical theory of the design of experiments, blocking is the arranging of experimental units that are similar to one another in groups (blocks) based on one or more variables. These variables are chosen carefully to minimize the affect of their variability on the observed outcomes.
