Tensile testing can be used to test creep in materials, a slow plastic deformation of the material from constant applied stresses over extended periods of time. Creep is generally aided by diffusion and dislocation movement.
Student's t-test is a statistical test used to test whether the difference between the response of two groups is statistically significant or not. It is any statistical hypothesis test in which the test statistic follows a Student's t -distribution under the null hypothesis. It is most commonly applied when the test statistic would follow a ...
Not to be confused with Wilcoxon rank-sum test. The Wilcoxon signed-rank test is a non-parametric rank test for statistical hypothesis testing used either to test the location of a population based on a sample of data, or to compare the locations of two populations using two matched samples. [1] The one-sample version serves a purpose similar ...
Miller test. The Miller test, also called the three-prong obscenity test, is the United States Supreme Court 's test for determining whether speech or expression can be labeled obscene, in which case it is not protected by the First Amendment to the United States Constitution and can be prohibited.

Three-point flexural test. The three-point bending flexural test provides values for the modulus of elasticity in bending , flexural stress , flexural strain and the flexural stress–strain response of the material. This test is performed on a universal testing machine (tensile testing machine or tensile tester) with a three-point or four ...
While white-box testing can be applied at the unit, integration, and system levels of the software testing process, it is usually done at the unit level. [33] It can test paths within a unit, paths between units during integration, and between subsystems during a system–level test.
In statistics, Welch's t-test, or unequal variances t-test, is a two-sample location test which is used to test the (null) hypothesis that two populations have equal means. It is named for its creator, Bernard Lewis Welch, and is an adaptation of Student's t -test, [1] and is more reliable when the two samples have unequal variances and ...
The undue burden standard is a constitutional test fashioned by the Supreme Court of the United States. The test, first developed in the late 20th century, is widely used in American constitutional law. [1] In short, the undue burden standard states that a legislature cannot make a particular law that is too burdensome or restrictive of one's fundamental rights.
