Psych 231 Research Methods in Psychology Class Experiment Class Experiment Print out the Class experiment listed on syllabus page exercise and bring it to labs this week Turn in your data sheets pass to front. Setups of an experiment should have only one variable that is changed at a time By having only one variable that is changed you can be fairly cert ain that the results of the experime nt were caused by that one variable Three types of variable s are Experimental Design.
