  2. Weighted median - Wikipedia

    en.wikipedia.org/wiki/Weighted_median

    The lower weighted median is 2 with partition sums of 0.49 and 0.5, and the upper weighted median is 3 with partition sums of 0.5 and 0.25. In the case of working with integers or non-interval measures, the lower weighted median would be accepted since it is the lower weight of the pair and therefore keeps the partitions most equal. However, it ...

  3. Forest plot - Wikipedia

    en.wikipedia.org/wiki/Forest_plot

    The chart portion of the forest plot will be on the right hand side and will indicate the mean difference in effect between the test and control groups in the studies. A more precise rendering of the data shows up in number form in the text of each line, while a somewhat less precise graphic representation shows up in chart form on the right.

  4. N50, L50, and related statistics - Wikipedia

    en.wikipedia.org/wiki/N50,_L50,_and_related...

    The median of the 32-element set L' is the average of the 16th smallest element, 4, and 17th smallest element, 8, so the N50 is 6. We can see that the sum of all values in the list L that are smaller than or equal to the N50 of 6 is 16 = 2+2+2+3+3+4 and the sum of all values in the list L that are larger than or equal to 6 is also 16 = 8+8.

  6. Medcouple - Wikipedia

    en.wikipedia.org/wiki/Medcouple

    The actual medcouple is the median of the bottom distribution, marked at 0.188994 with a yellow line. In statistics, the medcouple is a robust statistic that measures the skewness of a univariate distribution. [1] It is defined as a scaled median difference between the left and right half of a distribution.

  7. Biostatistics - Wikipedia

    en.wikipedia.org/wiki/Biostatistics

    The research plan might include the research question, the hypothesis to be tested, the experimental design, data collection methods, data analysis perspectives and costs involved. It is essential to carry the study based on the three basic principles of experimental statistics: randomization , replication , and local control.

  8. Hodges–Lehmann estimator - Wikipedia

    en.wikipedia.org/wiki/Hodges–Lehmann_estimator

    In statistics, the Hodges–Lehmann estimator is a robust and nonparametric estimator of a population's location parameter.For populations that are symmetric about one median, such as the Gaussian or normal distribution or the Student t-distribution, the Hodges–Lehmann estimator is a consistent and median-unbiased estimate of the population median.

  9. Alpha diversity - Wikipedia

    en.wikipedia.org/wiki/Alpha_diversity

    The nominal weight of the jth subunit is , which equals the proportion of data that the subunit contributes to the dataset. Large values of q lead to smaller alpha diversity than small values of q , because increasing q increases the effective weight given to those species with the highest proportional abundance and to those subunits with the ...
