For questions 49-52 read the following abstract: This experimental study assessed the effectiveness of fundraising messages. Based on recent findings regarding the effects of message framing and evidence, effective fundraising messages should combine abstract, statistical information with a negative message frame and anecdotal evidence with a positive message frame. In addition, building on research into social dilemmas, it was hypothesized that information about charity goal attainment (e.g., the contributions of others) should increase donation intentions. The hypotheses were tested in a 2 (goal attainment: yeso) * 2 (framing: positiveegative) x 2 (evidence: statistical/anecdotal) factorial design. Abstract information was more effective when combined with a negatively framed message, whereas anecdotal information was more effective when combined with a positive frame. In addition, donation intentions were higher for messages that addressed charity goal attainment issues. Which variables were manipulated as independent variables in this experiment? O Goal attainment, framing, and evidence O Abstract and anecdotal information Message framing and evidence Donation intentionsWhich variables served as dependent variables in this experiment? O Donation intentions O Abstract and anecdotal information Message framing and evidence O Goal attainment, framing, and evidenceWhich variable served as a subject variable in this experiment?
