Dataset 2: Some are your team members are interested in how the emotional states of students are impacted by the types of language that instructors use to encourage student learning. They conducted a study where they had a group of participants either watch a really sad movie just before class or a funny comedy right before attending class. This movie was used to induce either a negative or positive emotional state prior to learning. Afterward, participants went to class and were split into group for group work. The instructor came around and either emphasized success or failure to each group. For example, the instructor said either, “you all are really capable of succeeding and mastering this material” or the instructor said, “I hope you all know this information well because it’s really hard and you could fail.” Participants then went back to their desks and wrote an independent essay based on what they were working on with their groups. The essays were graded separately to see how individuals processed their own emotional state along with how the instructor spoke to them. Your team has one research question for this dataset: 1) How do essay scores differ between students who are in either a positive or negative mood and experience encouraging (success) messages from their instructor or threatening (failure) messages from their instructor? What type of statistical analysis do you need to use and why? Write your null and alternative hypotheses. What type of statistical analysis do you need to use and why?
