  2. Comparative research - Wikipedia

    en.wikipedia.org/wiki/Comparative_research

    Comparative research is a research methodology in the social sciences exemplified in cross-cultural or comparative studies that aims to make comparisons across different countries or cultures. A major problem in comparative research is that the data sets in different countries may define categories differently (for example by using different ...

  3. Null hypothesis - Wikipedia

    en.wikipedia.org/wiki/Null_hypothesis

    A statistical significance test starts with a random sample from a population. If the sample data are consistent with the null hypothesis, then you do not reject the null hypothesis; if the sample data are inconsistent with the null hypothesis, then you reject the null hypothesis and conclude that the alternative hypothesis is true. [3]

  4. Pilot experiment - Wikipedia

    en.wikipedia.org/wiki/Pilot_experiment

    In sociology, pilot studies can be referred to as small-scale studies that will help identify design issues before the main research is done.Although pilot experiments have a well-established tradition, their usefulness as a strategy for change has been questioned, at least in the domain of environmental management. [3]

  5. Quasi-experiment - Wikipedia

    en.wikipedia.org/wiki/Quasi-experiment

    A quasi-experiment is an empirical interventional study used to estimate the causal impact of an intervention on target population without random assignment.Quasi-experimental research shares similarities with the traditional experimental design or randomized controlled trial, but it specifically lacks the element of random assignment to treatment or control.

  6. Estimation statistics - Wikipedia

    en.wikipedia.org/wiki/Estimation_statistics

    Many significance tests have an estimation counterpart; [26] in almost every case, the test result (or its p-value) can be simply substituted with the effect size and a precision estimate. For example, instead of using Student's t-test, the analyst can compare two independent groups by calculating the mean difference and its 95% confidence ...

  7. Estimation - Wikipedia

    en.wikipedia.org/wiki/Estimation

    The sample provides information that can be projected, through various formal or informal processes, to determine a range most likely to describe the missing information. An estimate that turns out to be incorrect will be an overestimate if the estimate exceeds the actual result [3] and an underestimate if the estimate falls short of the actual ...

  8. Thematic analysis - Wikipedia

    en.wikipedia.org/wiki/Thematic_analysis

    Thematic analysis is often understood as a method or technique in contrast to most other qualitative analytic approaches – such as grounded theory, discourse analysis, narrative analysis and interpretative phenomenological analysis – which can be described as methodologies or theoretically informed frameworks for research (they specify ...

  9. 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.
