Blocking statistics - Math Glossary

WebIn the statistical theory of the design of experiments, blocking is the arranging of experimental units in groups (blocks) that are similar to one another. An example of a blocking factor might be the sex of a patient; by blocking on sex, this source of variability is controlled for, thus leading to greater accuracy. WebTo go back to the original measurement scale, just take the coded value and multiply it by "b" and add "a" or, X = b (coded value) + a. As an example, if the factor is temperature and the high setting is 65 o C and the low setting is 55 o C, then a = (65 + 55)/2 = 60 and b = (65 - 55)/2 = 5. The center point (where the coded value is 0) has a ... snap on screwdriver replacement shaft
