A new medicine, BeGone, claims to relieve a headache in ten minutes and last for up to six hours. Researchers running a clinical trial to test BeGones effectiveness assessed headache relief, as measured by self-report on a scale of 1 (no relief) to 10 (complete relief); specifically they were interested in whether there was significant difference in headache relief given BeGone treatment as compared to a placebo or no treatment at all. They tested three separate groups of people those who had a headache and took BeGone, those who had a headache and took a placebo, and those who had a headache but took nothing.

State (for each IV), whether it is between- or within-Ss. 1 Which test would be appropriate to analyze the data in this study? ?one-way independent groups ANOVA ?one-way repeated measures ANOVA ?two-way independent groups ANOVA ?two-way repeated measures ANOVA ?two-way mixed measures ANOVA 1 State whether the researchers should look for an interaction effect. If so, please draw a graph of a possible interaction that the researcher might observe and describe the interaction you have depicted. Questions 7 12. Researchers were interested in whether there was a significant difference in the effectiveness of biological gestures (e.g., pointing) in divert attention as compared to directional icons (e.g., arrows) or directional words (e.g., left) and whether the effect (if any) is significantly mediated by the length of time the directional cue is presented. Suppose the researchers asked study participants to move their eyes in the opposite direction of a directional cue and recorded Attachments: stat.docx
