Statistics- Children who experience school-related anxiety are the focus of a psychiatrist

| March 31, 2017

Question
Your answer must include: A) SPSS output; B) an appropriate graph from SPSS; C) a Results section in current APA style including a statistical statement (i.e., t(19) = 1.79, p = .049); a sentence summarizing the results “in English” (i.e., “There was a significant difference between the two groups on the variable…” or “There was no significant difference…”); and a decision about the null hypothesis.

For ANOVA problems: Report statistical findings and make statements for all main effects and interaction effects. Use Tukey’s test for any analyses requiring post hoc tests. Do not create a boxplot for the 2-way ANOVA–use the graph we typically use in the course for this type of test.

Children who experience school-related anxiety are the focus of a psychiatrist’s study. Specifically, the psychiatrist wants to measure whether a new program helps decrease feelings of anxiety in the short-term. He measures children’s self-reports of school-related anxiety before treatment on a standardized scale with a range of 0-12, with 12 being the most severe. He then administers the new program, and measures children’s self-reported anxiety after treatment. Does the new treatment decrease self-reported levels of school-related anxiety? Choose the correct test to analyze this question, set up the SPSS file, and run the analysis. Follow the directions under the table below. (16 pts)
