This strategy is advantageous because it moderates several threats to validity, and history effects in particular. [2] [4] Concurrent multiple baseline designs are also useful for saving time, since all participants are processed at once. The ability to retrieve complete data sets within well defined time constraints is a valuable asset while ...
The Solomon four-group design is a research method developed by Richard Solomon in 1949. [1] It is sometimes used in social science , psychology and medicine. It can be used if there are concerns that the treatment might be sensitized by the pre-test . [ 2 ]
In psychology, compensation is a strategy whereby one covers up, consciously or unconsciously, weaknesses, frustrations, desires, or feelings of inadequacy or incompetence in one life area through the gratification or (drive towards) excellence in another area. Compensation can cover up either real or imagined deficiencies and personal or ...
The use of a sequence of experiments, where the design of each may depend on the results of previous experiments, including the possible decision to stop experimenting, is within the scope of sequential analysis, a field that was pioneered [13] by Abraham Wald in the context of sequential tests of statistical hypotheses. [14]
The results of their experiments did not support these claims. Newell & Fernandez and Richter & Späth tested the non-compensatory prediction of the recognition heuristic and stated that "recognition information is not used in an all-or-none fashion but is integrated with other types of knowledge in judgment and decision making." [23]
Qualitative psychological research findings are not arrived at by statistical or other quantitative procedures. Quantitative psychological research findings result from mathematical modeling and statistical estimation or statistical inference. The two types of research differ in the methods employed, rather than the topics they focus on.
[5] [6] Compensatory methods such as TOPSIS allow trade-offs between criteria, where a poor result in one criterion can be negated by a good result in another criterion. This provides a more realistic form of modelling than non-compensatory methods, which include or exclude alternative solutions based on hard cut-offs. [ 7 ]
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.
