 It is a type of research where the researcher manipulates one variable while controlling the rest of the variables.  It is usually conducted to explain.

Reliability A measure of consistency. Can we get the same results when the same measure is used on another occasion? Measures in research should be reliable.

Variables noise or quiet test score IV DV The independent variable (IV) is what we manipulate. And the dependent variable (DV) is what we measure – because it depends on what we do IV DV noise or quiet test score

Extraneous Variables Extraneous variables are things that could have an effect on the results – if we don’t control for them There are two types of extraneous variables Situational: variables in the situation such as light, heat, noise Participant: variables within the participant such as personality, IQ, gender

Confounding variables Extraneous variables are the ones that could affect your research unless controlled. If you fail to control them and they do affect your research, they become confounding variables.
