Module 5 DQ 1Assume that you are interested in the relationship between Graduate Record Examinations (GRE) scores (the total of all subtests)and graduate school grade point averages (GPAs) at the end of their graduate programs. Conveniently, you have access to theGRE scores and GPAs of a large number of graduate students who have graduated from the electrical engineering master's19
program in an Ivy League university between 2000 and 2013. The Pearson correlation coefficient did not reach significance.What can you conclude from the data analysis? Can the result be generalized to all graduate students in electrical engineeringmaster's programs across the United States? Why or why not?Module 5 DQ 2A researcher asks the question "Is there a relationship between GRE total scores and GPAs in the master's programs in electricalengineering?" The researcher's null hypothesis states, "There is no correlation between GRE total score and GPA from anelectrical engineering master's program." The researcher's alternative hypothesis states, "There is a positive correlation betweenGRE total scores and GPA from an electrical engineering master's program."Are these valid hypotheses for the research question? Why or why not? What other observations can you make regarding thehypotheses and research question?Module 6 DQ 1Suppose you are interested in how children with severe autism experienced the receipt of special education assistance in publicschools. This population is characterized by underdevelopment of social cognition, social skills, and language skills. What is thebest method for collecting data to answer your research question? Why is this method best? How would you describe the researchdesign?Module 6 DQ 2( need to upload 6 documents to get 5 more unlocks)Suppose you are interested in how children with severe autism experienced the receipt of special education assistance in publicschools. This population is characterized by underdevelopment of social cognition, social skills, and language skills. How manychildren should be included in the study? Why? What are the factors considered in making this determination?Module 7 DQ 1Suppose you are interested in the behaviors of physicians that have high ratings of patient satisfaction. The research goal is toidentify the behaviors in the natural clinical settings of these successful physicians so that these behaviors can be built into thecurricula of medical preparation programs. The main data were collected by the video recording of five randomly selectedphysician-patient encounters from 10 physicians who have been rated highly by patients in a reliable satisfaction survey.
