Description These data are from a study aimed at reducing anxiety symptoms. We measured people’s anxiety before they took an anti-anxiety drug, and then we measured their anxiety again after they took the drug. Our hypothesis was that they would have lower anxiety scores after taking the drug than they did before taking the drug. 1. What is the value of t? 2. What is the value of p for this study (remember to consider whether it is a one-tailed or a two-tailed hypothesis)? 3. What were the means of the anxiety scores before and after they took the drug? 4. Was there a statistically significant difference between the two conditions? 5. Should you reject the null hypothesis? Turn in a PDF or word document of your SPSS output and a PDF or word document of your answers to the questions.

The attached data are from a study examining which of three instructors did the best job teaching their students. We measured how good of a job the instructors did by measuring their students’ final exam grades. Professors who did the best job teaching should have students who earned the highest grades. The research hypothesis is that there will be group differences. That is, some professors will do a better job than other professors. For the data, “ID” is the ID number of the student. “Instructor” is the instructor each student had. The instructors are labeled as 1, 2, or 3. “Postclass” is the grade each student had on the final exam. Run an ANOVA to see if the professors did differ in how well they did their jobs. What was the observe F value? What was the p value? Should you reject the null hypothesis? According to the post-hoc analyses, where were the significant group differences? Which instructor had the best performance? Turn in SPSS output and answers as a PDF or Word document. Attachments ANOVA SPSS assignment.sav
