After reading through the literature, the researcher decides to compare love and money. The researcher carefully constructs the variables, then recruits participants. Participants are assigned to the love or money group. Happiness was recorded using a self-report measure where higher scores indicate greater happiness. It was predicted that participants in the love condition would have higher happiness scores than those in the money condition.
