Document Summary

Usually used in drug- related studies where people might have strong expectations about drug effects. Is a special type of control group that is used to control for subjects". If the control group is given a placebo, then its assumes that all groups (the control and experimental groups) are equal. Cannot have a confounding variable in your variable. A variable that interferes with the results of the study. It affects the dependent variable so you don"t know whether the effects are caused by the independent variable or by the confounding variable (i. v d. v) Go back to the experiment and try to get rid of the confounding variable. By using this we assume that all individual difference variables are being evenly distributed among groups so that they are essentially equal. Measures the degree of relationship between two variables. There is no attempt to manipulate and control variables, rather naturally occurring variations or changes are measured to see if they are related.
