This technical use of the term confounding in the context of experimental design is an important one and is discussed at length in classic texts such as Chapter 6 of Cochran and Cox (1957).

A WitrynaConfounding: A situation in which a measure of association or relationship between exposure and outcome is distorted by the presence of another variable. Positive confounding (when the observed association is biased away from the null) and negative confounding (when the observed association is biased toward the null) both occur.
