Document Summary
Correlational research/association claims searching for associations. Two measured variables both variables are participant variables manipulated by a researcher; rather, each reflect individual differences. Ex: the reasons for fidgeting or sitting within a particular section were not. Some may be more prone to fidget: we can assess a frequency claim (one variable, we can assess an association claim. Do students who choose to sit in the front of the room fidget less than those who sit in the back: we can not assess a causal claim. We did not start with equal groups; we have not manipulated anything. Experimental research/causal claims searching for causation. One manipulated variable, one measured variable: start with two equal groups. Based on random assignment; this accounts for participant variable: manipulate one variable. Participant variables: individuals came into the lab with/without adhd and different study habits. Claims: frequency (avg number of work put in each month) and association (amount of work they time and adhd)
