researcher wanted to know if there is a link between a sedentary lifestyle and depression among college students. to conduct the study researcher compared the depression rates of 100 sedentary college students and 100 active college students. they defined a person as active if that person exercised more than 2 hours a week abs sedentary if they did not exercise at all. their data showed that college students who did not exercise at all had a higher rate of depression than those who did. can we conclude that sedentary life style causes depression? A. no. the sample size is not large enough to establish causation B. Yes. because the researchers studied both groups equally and defined their terms carefully. C. Yes because the sample size is large D. no because this was an observational study

A psychology instructor at a large university teaches statistics. There are 22 students in the class, and he has broken them into two groups. Each group has a different graduate assistant who is responsible for running separate breakout lecture and lab sections of the course. One graduate assistant (GA) has lots of experience teaching, while the other has more limited experience. The instructor wants to check for comparable learning across the two GAs, hoping students receive similar experiences (i.e., to find no difference). The data below are the scores (out of 100) of the students on the first midterm. Use it to test whether there is a difference between the groups. Group 1 (less experienced GA) Group 2 (more experienced GA) 60 70 65 85 69 72 58 83 57 81 59 69 52 65 72 75 70 79 65 71 75 80 Q: List the steps to obtaining all relevant statistical output in SPSS.

Scenario: Researchers were interested in how social situations can influence stress-induced eating. They grouped participants according to self-reported stress-induced eating habits: consistently eating more (hyperphagics) or eating less (hypophagics) when stressed. Each participant was then exposed to one of three social situations: (1) a social inclusion condition, where subjects were told that a confederate partner had approved of a video they had made answering some questions and was looking forward to meeting them, (2) a neutral condition, where they were told their partners could not meet them because their partners had to cancel their participation, or (3) a social exclusion condition, where they were told that their partner had decided not to meet them after viewing their video. Subjects were then given an ice cream taste test and the amount of ice cream consumed was measured. Question: What is the most appropriate statistical test to conduct given this scenario? Randomized…
