Variables that may affect the results of an experiment are described by the umbrella term "extraneous variable". extraneous variables that actually affect the result without experimenter knowledge is called a confounding variables eg. if the experimenter is testing verbal recall performance, hair color is not going to effect the results. hair color is an extraneous variable, but not compound. but whether or not a subject had a good nights sleep can have a huge effect on the ability to remember words. therefore sleep is a compound variable.

What is extraneous variable?

An extraneous factor is one that is not pertinent or relevant to what is being studied, for instance, in a research experiment. It may, however, have an unwanted impact if naturally present and not controlled or distributed evenly across groups. Example: You give the same test to two groups. One group was allowed to study, the other was not. The "study vs. no study" variable is what you are most interested in, and you have attempted to control for other variables that would not be considered relevant to your interest is the study versus no study variable. For instance, the gender of the subjects is not something you want to study in this research, so you make sure that both your study and your no-study subject groups are about the same in terms of gender distribution. You would also want to make sure that the two groups had roughly the same experience in terms of room temperature, time of day taking the test, amount of light to see by and so on so that the groups were differently primarily in whether they studied or not, and nothing else.
