What is an example of blocking?

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. 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.

Which one is an example of blocking psychology?

For important nuisance variables, blocking will yield higher significance in the variables of interest than randomizing.

What is blocking in a study?

What is Blocking? Blocking is where you control sources of variation (“nuisance variables“) in your experimental results by creating blocks (homogeneous groups). Treatments are then assigned to different units within each block.

What does Misattribution mean in psychology?

Definition. Misattribution of arousal refers to the idea that physiological arousal can be perceived to stem from a source that is not actually the cause of the arousal, which may have implications for the emotions one experiences.
