  2. Embedded case study - Wikipedia

    en.wikipedia.org/wiki/Embedded_case_study

    An embedded case study is a case study containing more than one sub-unit of analysis (Yin, 2003). Similar to a case study, an embedded case study methodology provides a means of integrating quantitative and qualitative methods into a single research study (Scholz & Tietje, 2002; Yin 2003). However, the identification of sub-units allows for a ...

  3. Median absolute deviation - Wikipedia

    en.wikipedia.org/wiki/Median_absolute_deviation

    The population MAD is defined analogously to the sample MAD, but is based on the complete population rather than on a sample. For a symmetric distribution with zero mean, the population MAD is the 75th percentile of the distribution. Unlike the variance, which may be infinite or undefined, the population MAD is always a finite number.

  4. Probabilistic design - Wikipedia

    en.wikipedia.org/wiki/Probabilistic_design

    Meshfree methods; Analytical methods (refer to classical design principles) Additionally, there are many statistical methods used to quantify and predict the random variability in the desired measurable. Some methods that are used to predict the random variability of an output include: the Monte Carlo method (including Latin hypercubes); [12]

  5. Methodology - Wikipedia

    en.wikipedia.org/wiki/Methodology

    However, many theorists emphasize the differences between the terms "method" and "methodology". [ 1 ] [ 7 ] [ 2 ] [ 11 ] In this regard, methodology may be defined as "the study or description of methods" or as "the analysis of the principles of methods, rules, and postulates employed by a discipline".

  6. Research design - Wikipedia

    en.wikipedia.org/wiki/Research_design

    There are many ways to classify research designs. Nonetheless, the list below offers a number of useful distinctions between possible research designs. A research design is an arrangement of conditions or collection. [5] Descriptive (e.g., case-study, naturalistic observation, survey) Correlational (e.g., case-control study, observational study)

  7. Analytic and enumerative statistical studies - Wikipedia

    en.wikipedia.org/wiki/Analytic_and_enumerative...

    Deming summarized the distinction between enumerative and analytic studies as follows: [2] Enumerative study: A statistical study in which action will be taken on the material in the frame being studied. Analytic study: A statistical study in which action will be taken on the process or cause-system that produced the frame being studied.

  8. Difference in differences - Wikipedia

    en.wikipedia.org/wiki/Difference_in_differences

    Difference in differences (DID [1] or DD [2]) is a statistical technique used in econometrics and quantitative research in the social sciences that attempts to mimic an experimental research design using observational study data, by studying the differential effect of a treatment on a 'treatment group' versus a 'control group' in a natural experiment. [3]

  9. Multimethodology - Wikipedia

    en.wikipedia.org/wiki/Multimethodology

    Multimethodology or multimethod research includes the use of more than one method of data collection or research in a research study or set of related studies.Mixed methods research is more specific in that it includes the mixing of qualitative and quantitative data, methods, methodologies, and/or paradigms in a research study or set of related studies.
