  2. Pre- and post-test probability - Wikipedia

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

    In clinical practice, post-test probabilities are often just estimated or even guessed. This is usually acceptable in the finding of a pathognomonic sign or symptom, in which case it is almost certain that the target condition is present; or in the absence of finding a sine qua non sign or symptom, in which case it is almost certain that the target condition is absent.

  3. Likelihood ratios in diagnostic testing - Wikipedia

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

    Posttest probability = Posttest odds / (Posttest odds + 1) Alternatively, post-test probability can be calculated directly from the pre-test probability and the likelihood ratio using the equation: P' = P0 × LR/(1 − P0 + P0×LR), where P0 is the pre-test probability, P' is the post-test probability, and LR is the likelihood ratio. This ...

  4. Dunnett's test - Wikipedia

    en.wikipedia.org/wiki/Dunnett's_test

    Dunnett's test's calculation is a procedure that is based on calculating confidence statements about the true or the expected values of the differences , thus the differences between treatment groups' mean and control group's mean. This procedure ensures that the probability of all statements being simultaneously correct is equal to a specified ...

  5. Do while loop - Wikipedia

    en.wikipedia.org/wiki/Do_while_loop

    Control flow. v. t. e. In many computer programming languages, a do while loop is a control flow statement that executes a block of code and then either repeats the block or exits the loop depending on a given boolean condition. The do while construct consists of a process symbol and a condition. First the code within the block is executed.

  6. Tukey's range test - Wikipedia

    en.wikipedia.org/wiki/Tukey's_range_test

    Tukey's range test, also known as Tukey's test, Tukey method, Tukey's honest significance test, or Tukey's HSD (honestly significant difference) test, [1] is a single-step multiple comparison procedure and statistical test. It can be used to correctly interpret the statistical significance of the difference between means that have been selected ...

  7. Testing effect - Wikipedia

    en.wikipedia.org/wiki/Testing_effect

    The testing effect (also known as retrieval practice, active recall, practice testing, or test-enhanced learning) [1][2][3] suggests long-term memory is increased when part of the learning period is devoted to retrieving information from memory. [4] It is different from the more general practice effect, defined in the APA Dictionary of ...

  8. Between-group design experiment - Wikipedia

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

    Between-group design experiment. In the design of experiments, a between-group design is an experiment that has two or more groups of subjects each being tested by a different testing factor simultaneously. This design is usually used in place of, or in some cases in conjunction with, the within-subject design, which applies the same variations ...
