PSYC 354 Hypothesis Testing Assignment: Analyzing CPT vs. PE Effectiveness Questions With 100% Correct Answers.

Research Question 1: Is Cognitive Processing Therapy (CPT) more effective in treating PTSD than Prolonged Exposure therapy (PE)? 1. Does this question represent a correlational or experimental research design? Why? ANSWER: (4 pts) This question represents an experimental research design because it is interested in the difference between CPT and PE regarding effectiveness in treating PTSD. 2. Which of the two models you learned about in the presentation would state that there is nothing interesting going on between CPT and PE in treating PTSD? ANSWER: (4 pts) The Null Model would state that there is nothing going on between CPT and PE. 3. State the alternative hypothesis for this study. ANSWER: (4 pts) H1: “Cognitive Processing Therapy (CPT) will be significantly more effective in treating PTSD than Prolonged Exposure therapy (PE).” 4. State the null hypothesis for this study ANSWER: (4 pts) H0: “Cognitive Processing Therapy (CPT) will not be significantly more effective in treating PTSD than Prolonged Exposure therapy (PE).” 5. Are your hypotheses directional or non-directional? How do you know this? ANSWER: (4 pts) The hypotheses are directional because the research question seeks to find if one treatment method is more effective than the other. The word “more” signifies that the test is a one-tailed and right tailed test. 6. Suppose you run the study, and the results come out with a p value of .23. What can you conclude about the difference between the treatments? ANSWER: (5 pts) The p value of .23 leads me to conclude that the difference between CPT and PE is not significant.
