Matched pair testing is used to detect discrimination. The focus is to determine the presence of disparate treatment in the offering of goods and services during the sales process.

A paired difference test is designed for situations where there is dependence between pairs of measurements (in which case a test designed for comparing two independent samples would not be appropriate). That applies in a within-subjects study design, i.e., in a study where the same set of subjects undergo both of the conditions being compared.
Matching is a statistical technique that evaluates the effect of a treatment by comparing the treated and the non-treated units in an observational study or quasi-experiment (i.e. when the treatment is not randomly assigned).
For two matched samples, it is a paired difference test like the paired Student's t-test (also known as the "t-test for matched pairs" or "t-test for dependent samples"). The Wilcoxon test is a good alternative to the t-test when the normal distribution of the differences between paired individuals cannot be assumed. Instead, it assumes a ...
The sign test is a statistical test for consistent differences between pairs of observations, such as the weight of subjects before and after treatment. Given pairs of observations (such as weight pre- and post-treatment) for each subject, the sign test determines if one member of the pair (such as pre-treatment) tends to be greater than (or less than) the other member of the pair (such as ...
The pairs are e.g. either one person's pre-test and post-test scores or between-pairs of persons matched into meaningful groups (for instance, drawn from the same family or age group: see table). The constant μ 0 is zero if we want to test whether the average of the difference is significantly different.
I ordered a pair of, er, Pair glasses with black frames and a navy-blue top, because I'm boring. My only regret is that I didn't choose something fun like The Retro Batman.
Besides amplifiers, discrete JFET matched pairs are also used in the design of voltage controlled resistors, voltage controlled current sources, current to voltage converters, programmable gain circuits, voltmeters, phasers and a wide range of analog computational circuits like absolute value circuits These blocks often are designed with ...
