  2. Jonckheere's trend test - Wikipedia

    en.wikipedia.org/wiki/Jonckheere's_Trend_Test

    In statistics, the Jonckheere trend test [1] (sometimes called the Jonckheere–Terpstra [2] test) is a test for an ordered alternative hypothesis within an independent samples (between-participants) design. It is similar to the Kruskal-Wallis test in that the null hypothesis is that several independent samples are from the same population ...

    The AUT measures a certain level of divergent thinking; exploring multiple answers using creativity [1] It doesn't compare to a traditional test that looks for a specific solution. [citation needed] As a result, from the AUT it is measured in four ways: [citation needed] Fluency: the number of other uses you can think of, from the original object

  4. Repeated measures design - Wikipedia

    en.wikipedia.org/wiki/Repeated_measures_design

    This test is not recommended given more than 2 levels of the within-subjects factor because the assumption of sphericity is commonly violated in such cases. Alternative Univariate test [6] —These tests account for violations to the assumption of sphericity, and can be used when the within-subjects factor exceeds 2 levels. The F statistic is ...

  5. Alternative hypothesis - Wikipedia

    en.wikipedia.org/wiki/Alternative_hypothesis

    The statement that is being tested against the null hypothesis is the alternative hypothesis. [2] Alternative hypothesis is often denoted as H a or H 1. In statistical hypothesis testing, to prove the alternative hypothesis is true, it should be shown that the data is contradictory to the null hypothesis. Namely, there is sufficient evidence ...

  6. Friedman test - Wikipedia

    en.wikipedia.org/wiki/Friedman_test

    The Wilcoxon signed-rank test is a nonparametric test of nonindependent data from only two groups. The Skillings–Mack test is a general Friedman-type statistic that can be used in almost any block design with an arbitrary missing-data structure. The Wittkowski test is a general Friedman-Type statistics similar to Skillings-Mack test. When the ...

  7. Test method - Wikipedia

    en.wikipedia.org/wiki/Test_method

    A test method is a method for a test in science or engineering, such as a physical test, chemical test, or statistical test. It is a definitive procedure that produces a test result. [ 1 ] In order to ensure accurate and relevant test results, a test method should be "explicit, unambiguous, and experimentally feasible.", [ 2 ] as well as ...

    The Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM) coordinates U.S. federal government evaluation of new, revised, and alternative test methods. Alternative methods are methods for safety testing of chemicals and chemical products that use fewer or no animals or that minimize or prevent animal pain and ...

  9. Construct validity - Wikipedia

    Another method is the known-groups technique, which involves administering the measurement instrument to groups expected to differ due to known characteristics. Hypothesized relationship testing involves logical analysis based on theory or prior research. [6] Intervention studies are yet another method of evaluating construct validity ...
