Practice: Repeated-Measures ANOVA

In this activity, students will take data from a fictitious design to practice conducting a Repeated-Measures Analysis of Variance (ANOVA). First, provide students with the research scenario and the accompanying questions to have them determine the research design, statistical analysis to use, and independent and dependent variables. Next, have students set up a data file

Exemplar Study: Do Graphic Warnings Make Cigarettes Less Cool? (Mixed Design)

This study examined the effectiveness of graphic warnings (i.e., pictures) for reducing the appeal of tobacco products. In the study, researchers exposed smokers and nonsmokers to combinations of large versus small warning labels and the inclusion versus omission of graphic pictures on three types of tobacco products. For the within-subjects component, each participant saw advertisements

Exemplar Study: Does Cuteness Make Us Careful? (Mixed Design)

This article examined how the perception of cuteness influences behavioral carefulness, enhancing people’s ability to care for infants. While researchers took physiological measures of heart activity and skin conductance, they exposed participants to a slide show of pictures of either infant animals (kittens and puppies) previously judged as very cute or adult animals (cats and

Exemplar Study: Can You Accurately Judge Romantic Interest? (Mixed Design)

This study sought to determine whether a third party could discern romantic interest between two strangers. To test this, male and female observers watched video clips of speed-dating situations to determine the individual speed dater’s level of romantic interest toward the speed-dating partner. Participants observed clips of different lengths (10 vs. 30 s), and from

Exemplar Study: Must Be Love on the Brain (Within-Subjects/Repeated-Measures Design)

This research focused on the brain functioning of people in love. Participants who rated themselves as being intensely in love, viewed a photo of their beloved, did a distracter task, and then viewed a photo of a neutral acquaintance while researchers took functional magnetic resonance imagery (fMRI). Each participant repeated the procedure six times. When

Lecture Slides: Pie Taste Test (MultiGroup / Repeated-Measures Design Demonstration)

In this demonstration/activity (with PowerPoint slides) four student volunteers have the opportunity to provide taste ratings for several types of pie.  Instructors would need to provide plates, napkins, utensils, and the 4 types of pie. Type of pie can obviously vary, but students seem to be more engaged when there is an obvious “cheap” kind

Lecture Slides: Listen to the Music (Mixed Design Demonstration)

In this activity all of the students in class have the opportunity to listen to five different songs,and provide ratings of how energized they feel after each song. Instructors would need to insert the five music clips into the PowerPoint (details provided on the slide below). For the between-subjects variable, students are randomly assigned to
