Document Summary

An independent variable is the variable that is manipulated in the experiment (creates change) Dependent variable is the outcome variable that is measured in an experiment (the effect) Manipulated variable, is when there are two different levels of the independent variable. Experimental condition (one of multiple different experimental levels) Random assignment (participants are randomly allocated to a group) Between-subjects variable (one level of an independent variable is applied to some study participants but not others) Within-subjects variable or repeated measures design (a person is measured each time after being exposed to two or more levels of the independent variable) Order effect (experiencing the conditions in the same order may create a bias effect, therefore they must randomly determine order so that participants receive different orders of conditions) Subject variables (classification variables that are not manipulated) Independent variables can be subject variables (personality variables used to group participants)
