  2. Blocking (statistics) - Wikipedia

    en.wikipedia.org/wiki/Blocking_(statistics)

    Blocking evolved over the years, leading to the formalization of randomized block designs and Latin square designs. [1] Today, blocking still plays a pivotal role in experimental design, and in recent years, advancements in statistical software and computational capabilities have allowed researchers to explore more intricate blocking designs.

    Blockage discount is an art-business-related and legal term of art for referring to the money discount assigned to a group of artworks by a single artist when that group of works is to be released to market as a group rather than individually.

    Crochet samples during blocking. After soaking in hot water these items were shaped and laid to dry on a towel. Pins hold some examples in the desired shape. Knitted scarf during blocking. In knitting, crochet and other handmade textile arts, blocking is a

  6. Friedman test - Wikipedia

    en.wikipedia.org/wiki/Friedman_test

    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 data do not contain any missing value, it gives the same result as Friedman test.

  7. Nuisance variable - Wikipedia

    en.wikipedia.org/wiki/Nuisance_variable

    If the problem is to derive the theoretical properties, such as the mean, variance and covariances of quantities that would be observed, then the intermediate variables are nuisance variables. [ 1 ] The related term nuisance factor has been used [ 2 ] in the context of block experiments , where the terms in the model representing block-means ...

  9. Block design - Wikipedia

    en.wikipedia.org/wiki/Block_design

    Block designs may or may not have repeated blocks. Designs without repeated blocks are called simple, [3] in which case the "family" of blocks is a set rather than a multiset. In statistics, the concept of a block design may be extended to non-binary block designs, in which blocks may contain multiple copies of an element (see blocking ...
