Scenario 2: Use the following information for the next 6 questions. Researcher wants to compare three Types of Therapy [Behavior Therapy (BT), Cognitive Therapy (CT), and Cognitive-Behavior Therapy (CBT)] to determine which therapy works best in terms of increasing Self-Esteem. The researcher selects a sample of individuals who have been diagnosed with clinical depression of size 21 (N = 21) to test the research hypothesis (alternative hypothesis) that there is a difference in the ability of the three therapies to increase Self-Esteem. The 21 participants are randomly assigned to each type of therapy (BT, CT, and CBT). Each participant receives their assigned therapy for a 6-month period. At the end of the 6-month period, the researcher administers a standardized test of Self-Esteem to each participant (lhigh numbers indicate higher Self-Esteem). The data are listed below. The researcher wants to minimize the probability of making a Type I Error. Subject BT (X - m) (X-M)^2 CT (X - m) (X-M)^2 CBT (X - m) (X-M)^2 Mean 1 82 6 36 80 8 64 78 10 100 80 2 80 4 16 76 4 16 72 4 16 76 3 78 2 4 74 2 4 70 2 4 74 4 76 0 0 72 0 0 68 0 0 72 5 74 -2 4 70 -2 4 66 -2 4 70 6 72 -4 16 68 -4 16 64 -4 16 68 7 70 -6 36 64 -8 64 58 -10 100 64 GRAND MEAN MEAN 76 0 72 0 68 0 72 SS 112 168 240 N 7 7 7 k 3 3 Question 21 Scenario 2: What is the correct decision for this statistical test of the means? Group of answer choices Reject the alternative hypothesis. Fail to Reject the alternative hypothesis. Reject the null hypothesis. Fail to Reject the null hypothesis. None of these are correct. Question 22 Scenario 2: Based on the results of the overall (Omnibus) ANOVA, describe the results in “plain English”? Group of answer choices (a) CT raises Self-Esteem significantly more than BT (b) CBT raises Self-Esteem significantly more than BT (c) CBT Raises Self-Esteem significantly more than CT (d) There is a significant difference in the types of therapy; however, we do not yet know where the difference is located. (e) There is no difference in the types of therapy in terms of raising Self-Esteem

A magazine advertisement claims that wearing a magnetized bracelet will reduce arthritis pain in those who suffer from arthritis. A medical researcher tests this claim with 233 arthritis sufferers randomly assigned either to wear a magnetized bracelet or to wear a placebo bracelet. The researcher records the proportion of each group who report relief from arthritis pain after 6 weeks. After analyzing the data, he fails to reject the null hypothesis. Which of the following are valid interpretations of his findings? There may be more than one correct answer. a. The magnetized bracelets are not effective at reducing arthritis pain. b. There's insufficient evidence that the magnetized bracelets are effective at reducing arthritis pain. c. The magnetized bracelets had exactly the same effect as the placebo in reducing arthritis pain. d. There were no statistically significant differences between the magnetized bracelets and the placebos in reducing arthritis pain.
(Critical Thinking) Dr. Al Numan wonders if the drug methotrexate (primarily an immunosuppressant, used to treat lupus) will have more psychological effects on schizophrenics being treated for lupus than the general population. They recruit 50 participants diagnosed with schizophrenia and lupus, placing them on an appropriate dosage of methotrexate, asking them to record any new or changing symptoms over the course of 3 months. Results show that many participants report a small reduction in their positive symptoms, especially those in earlier stages of schizophrenia. Dr. Al Numan concludes that methotrexate is more psychologically beneficial to schizophrenics with lupus than the general population.
