Randomized Block Design

Randomized Block Design

In the statistical theory of the design of experiments, blocking is the arranging of experimental units in groups (blocks) that are similar to one another. Typically, a blocking factor is a source of variability that is not of primary interest to the experimenter. 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.

    Get behind me, Satan! You are a stumbling block to me; for you are setting your mind not on divine things but on human things.

    To nourish children and raise them against odds is in any time, any place, more valuable than to fix bolts in cars or design nuclear weapons.
