2. Pre- and post-test probability - Wikipedia

   en.wikipedia.org/wiki/Pre-_and_post-test_probability

   The individual's pre-test probability was more than twice the one of the population sample, although the individual's post-test probability was less than twice the one of the population sample (which is estimated by the positive predictive value of the test of 10%), opposite to what would result by a less accurate method of simply multiplying ...

3. Likelihood ratios in diagnostic testing - Wikipedia

   en.wikipedia.org/wiki/Likelihood_ratios_in...

   In fact, post-test probability, as estimated from the likelihood ratio and pre-test probability, is generally more accurate than if estimated from the positive predictive value of the test, if the tested individual has a different pre-test probability than what is the prevalence of that condition in the population.

4. Between-group design experiment - Wikipedia

   en.wikipedia.org/wiki/Between-group_design...

   The main disadvantage with between-group designs is that they can be complex and often require a large number of participants to generate any useful and reliable data. For example, researchers testing the effectiveness of a treatment for severe depression might need two groups of twenty patients for a control and a test group. If they wanted to ...

5. Student's t-test - Wikipedia

   en.wikipedia.org/wiki/Student's_t-test

   Paired samples t-tests typically consist of a sample of matched pairs of similar units, or one group of units that has been tested twice (a "repeated measures" t-test). A typical example of the repeated measures t-test would be where subjects are tested prior to a treatment, say for high blood pressure, and the same subjects are tested again ...

6. Design of experiments - Wikipedia

   en.wikipedia.org/wiki/Design_of_experiments

   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 [12] by Abraham Wald in the context of sequential tests of statistical hypotheses.

   The first two groups receive the evaluation test before and after the study, as in a normal two-group trial. The second groups receive the evaluation only after the study. [citation needed] The effectiveness of the treatment can be evaluated by comparisons between groups 1 and 3 and between groups 2 and 4. [citation needed]. In addition, the ...
