ONE-WAY ANOVA

The One-way ANOVA and Cumulative Knowledge Question Student Name Institution Professor Name Course Date The One-way ANOVA and Cumulative Knowledge Question Problem Set 1: The One-way ANOVAResearch Scenario: A group of clinical psychologists conducts a randomized clinical trial examining psychosocial and pharmaceutical treatments, alone or in combination, for Social Anxiety Disorder (SAD). Participants who have been diagnosed with SAD are randomly assigned to one of three treatment groups: cognitive behavioral therapy (CBT); Paxil ® (a common SSRI prescribed to patients with SAD); and CBT + Paxil ®. The participants are assessed after 6 months of treatment using the Social Avoidance and Distress Scale (SADS; Watson and Friend, 1969), where higher scores indicate higher levels of social anxiety. Their SADS scores are in the table below.Using this table, enter the data into a new SPSS data file and run a one-way ANOVA to test whether there is a difference in SADS scores between the three treatments. Remember to put your initials within any and all variable names. Create a boxplot to show the difference between the groups. Follow the directions below the table to complete the homework.Problem Set 1: The One-way ANOVAResearch Scenario: A group of clinical psychologists conducts a randomized clinical trial examining psychosocial and pharmaceutical treatments, alone or in combination, for Social Anxiety Disorder (SAD).

Include your boxplot as an APA-style Figure, with figure number and title, as demonstrated in the Results Section presentation. (Results = 12 pts; Figure = 8 pts) Results Whether there is a Difference in SADS Scores between the Three Treatments From the ANOVA results, the p-value is 0.289, which is more than 0.05 significance level. It demonstrates that the SADS scores between the three treatments are not significantly related. Therefore, there is no difference in SADS Scores between the three treatments. Problem Set 2: The One-way ANOVAResearch Scenario: A developmental psychologist is studying the progression of object permanence (the understanding that an object still exists even if it’s out of sight). She tests three groups of infants – ten who are 9 months old, eight who are 12 months old, and ten who are 15 months old. She presents each of the infants with 10 trials. On each trial, a toy is first shown to the child and then covered with a piece of cloth. The infant demonstrates o...
