Experimental Research Designs “A correlational study determines whether or not two variables are correlated. This means to study whether there is an increase or decrease in one variable corresponds to an increase or decrease in the other variable” (Cherry‚ 2012). In most correlation studies there is a relationship between both variables that had a change‚ while in others there wasn’t necessarily causation between the two (Cherry‚ 2012). An experimental design is one in which the researcher manipulates
