1. An Educational Psychologist is interested in examining the effects of different learning techniques on test comprehension in undergraduate students. The Educational Psychologist conducts a study in which undergraduate students are brought into the lab and randomly assigned to one of four different learning technique groups, with eight different undergraduate student participants in each group. Each group is asked to review the same textbook passage (i.e., 10 pages taken from a textbook) using one of the following four learning techniques: re-reading text, highlighting text, visual imagery, and summarizing text. After the allotted study time has ended, they complete a test with twenty-five questions evaluating their comprehension of the textbook passage. Their tests scores (i.e., number of correct answers on the test) are available in the data file Learning_Techniques.csv. Use alpha = .05 for any decisions you make about the null hypotheses and statistical significance. Use these data to answer the following questions: a. State the null and alternative hypotheses for the research question: Does test comprehension in undergraduate students differ depending on the type of learning techniques used? b. Do the data meet all the assumptions of the appropriate statistical analysis? Why or why not? (please include screenshots of the relevant part of the jamovi output to support your answers) c. Calculate by hand df total, df within, and dfbetween. Please show your work
