  2. Biological tests of necessity and sufficiency - Wikipedia

    en.wikipedia.org/wiki/Biological_tests_of...

    Tests of sufficiency in biology are used to determine if the presence of an element permits the biological phenomenon to occur. In other words, if sufficient conditions are met, the targeted event is able to take place. However, this does not mean that the absence of a sufficient biological element inhibits the biological event from occurring.

  3. False positives and false negatives - Wikipedia

    en.wikipedia.org/wiki/False_positives_and_false...

    The specificity of the test is equal to 1 minus the false positive rate. In statistical hypothesis testing, this fraction is given the Greek letter α, and 1 − α is defined as the specificity of the test. Increasing the specificity of the test lowers the probability of type I errors, but may raise the probability of type II errors (false ...

  4. Model-dependent realism - Wikipedia

    en.wikipedia.org/wiki/Model-dependent_realism

    Model-dependent realism is a view of scientific inquiry that focuses on the role of scientific models of phenomena. [1] It claims reality should be interpreted based upon these models, and where several models overlap in describing a particular subject, multiple, equally valid, realities exist.

  5. Constructive realism - Wikipedia

    en.wikipedia.org/wiki/Constructive_realism

    Within the philosophy of measurement, Jane Loevinger [1] described the relation between a construct (scientific model or construction of reality) and the reality itself. Now referred to as "Construct Realism", recognized chiefly in philosophy of measurement (psychometrics), Loevinger's view is expressed in the following quote in the context of ...

  6. Scientific realism - Wikipedia

    en.wikipedia.org/wiki/Scientific_realism

    Scientific realism is the view that the universe described by science is real regardless of how it may be interpreted. A believer of scientific realism takes the universe as described by science to be true (or approximately true), because of their assertion that science can be used to find the truth (or approximate truth) about both the physical and metaphysical in the Universe.

  7. Test (biology) - Wikipedia

    en.wikipedia.org/wiki/Test_(biology)

    In biology, a test is the hard shell of some spherical marine animals and protists, notably sea urchins and microorganisms such as testate foraminiferans, radiolarians, and testate amoebae. The term is also applied to the covering of scale insects. The related Latin term testa is used for the hard seed coat of plant seeds.

  8. Reality testing - Wikipedia

    en.wikipedia.org/wiki/Reality_testing

    Reality testing is the psychotherapeutic function by which the objective or real world and one's relationship to it are reflected on and evaluated by the observer. This process of distinguishing the internal world of thoughts and feelings from the external world is a technique commonly used in psychoanalysis and behavior therapy, and was originally devised by Sigmund Freud.

  9. Fluorescence in situ hybridization - Wikipedia

    en.wikipedia.org/wiki/Fluorescence_in_situ...

    In biology, a probe is a single strand of DNA or RNA that is complementary to a nucleotide sequence of interest. RNA probes can be designed for any gene or any sequence within a gene for visualization of mRNA , [ 3 ] [ 4 ] [ 5 ] lncRNA [ 6 ] [ 7 ] [ 8 ] and miRNA in tissues and cells.
