Example organisms used for high-content screening include the fruit fly (Drosophila melanogaster), zebrafish (Danio rerio) and mice (Mus musculus). [13] In some instances the term phenotypic screening is used to include the serendipitous findings that occur in clinical trial settings particularly when new and unanticipated therapeutic effects ...
Biological tests of necessity and sufficiency refer to experimental methods and techniques that seek to test or provide evidence for specific kinds of causal relationships in biological systems. A necessary cause is one without which it would be impossible for an effect to occur, while a sufficient cause is one whose presence guarantees the ...
Student's t-test, Analysis of variance, Mann–Whitney U test Repeated measures design 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.
In medical diagnosis, test sensitivity is the ability of a test to correctly identify those with the disease (true positive rate), whereas test specificity is the ability of the test to correctly identify those without the disease (true negative rate). If 100 patients known to have a disease were tested, and 43 test positive, then the test has ...
Unlike the computer adaptive test before August 2011, the GRE General Test is a multistage test, where the examinee's performance on earlier sections determines the difficulty of subsequent sections, using a technique known as computer-adaptive testing. This format allows the examined person to freely move back and forth between questions ...

The test of foraminifera, a group of single-celled organisms, is extremely evolutionarily diverse.Many different methods of constructing the test are present, from lacking a test in Reticulomyxa, proteinaceous tests in the "allogromiids", agglomerated tests made from foreign particles in many groups including textulariids, silica tests in silicoloculinids, and aragonite or calcite tests in ...
Several types of screening exist: universal screening involves screening of all individuals in a certain category (for example, all children of a certain age). Case finding involves screening a smaller group of people based on the presence of risk factors (for example, because a family member has been diagnosed with a hereditary disease).
