A data frame with 51 rows and 2 variables:

group: Factor with three levels - challng, comfort, control
motivation: Student motivation score (dependent variable)

How do you think you would react to feedback that gave encouragement and reassurance, or, instead, encouragement and challenge? Carol Dweck and her colleagues have investigated many such questions about how people respond to different types of feedback. This data set comes from Dweck's research group. Rattan et al. (2012) asked their college student participants to imagine they were undertaking a math course and had just received a low score (65 first test of the year. Participants were assigned randomly into three groups, which received different feedback along with the low score. The Comfort group received positive encouragement and also reassurance, the Challenge group received positive encouragement and also challenge, and the Control group received just the positive encouragement. Participants then responded to a range of questions about how they felt about the course and their professor. The dependent variable included here is ratings of their own motivation towards mathematics after they had received the feedback.
