  2. Qualitative variation - Wikipedia

    en.wikipedia.org/wiki/Qualitative_variation

    An index of qualitative variation (IQV) is a measure of statistical dispersion in nominal ... is as a ratio of observed differences to maximum differences.

  3. Sample size determination - Wikipedia

    en.wikipedia.org/wiki/Sample_size_determination

    Rather than relying on predetermined formulas or statistical calculations, it involves a subjective and iterative judgment throughout the research process. In qualitative studies, researchers often adopt a subjective stance, making determinations as the study unfolds. Sample size determination in qualitative studies takes a different approach.

  4. Statistical dispersion - Wikipedia

    en.wikipedia.org/wiki/Statistical_dispersion

    A measure of statistical dispersion is a nonnegative real number that is zero if all the data are the same and increases as the data become more diverse.. Most measures of dispersion have the same units as the quantity being measured.

  5. Sample maximum and minimum - Wikipedia

    en.wikipedia.org/wiki/Sample_maximum_and_minimum

    In statistics, the sample maximum and sample minimum, also called the largest observation and smallest observation, are the values of the greatest and least elements of a sample. [1] They are basic summary statistics , used in descriptive statistics such as the five-number summary and Bowley's seven-figure summary and the associated box plot .

  6. Variation ratio - Wikipedia

    en.wikipedia.org/wiki/Variation_ratio

    The variation ratio is a simple measure of statistical dispersion in nominal distributions; it is the simplest measure of qualitative variation. It is defined as the proportion of cases which are not in the mode category:

  7. Theoretical sampling - Wikipedia

    en.wikipedia.org/wiki/Theoretical_sampling

    Theoretical sampling helps in exploring various hibernating research questions that are eventually evident in the data collection as a theory. According to Glaser and Holton (2004), Grounded theory that has a data collecting inclination towards theoretical sampling was first derived from qualitative sampling.

  8. Repeated measures design - Wikipedia

    en.wikipedia.org/wiki/Repeated_measures_design

    Repeated measures design is a research design that involves multiple measures of the same variable taken on the same or matched subjects either under different conditions or over two or more time periods. [1]

  9. Median absolute deviation - Wikipedia

    en.wikipedia.org/wiki/Median_absolute_deviation

    In statistics, the median absolute deviation (MAD) is a robust measure of the variability of a univariate sample of quantitative data.It can also refer to the population parameter that is estimated by the MAD calculated from a sample.
