Question

1. A researcher is interested in examining whether there is an association between gender and DSM-5 diagnoses among a sample of male and female patients in a state psychiatric facility. After completing extensive psychological testing and a comprehensive structured clinical interview, the researcher is able to classify the patients into the following broad diagnostic categories. From the data reported in the table below, can the researcher conclude that gender and diagnosis are associated? Test at .05. DSM-5 Diagnosis Mood Disorder | Psychotic Disorder | Antisocial Personality Gender Male | 40 | 30 | 50 | 120 Female | 30 | 40 | 10 | 80 70 | 70 | 60 | 200 a. Which type of Chi-Square test is appropriate for the above example? Why? b. State your null and alternative hypotheses for this study. c. Report the calculated ?² value. Show all work (this includes the formula and a photo). d. Report the critical ?² value (from table). e. Make a decision regarding the null hypothesis (i.e., accept or reject H?). f. Why did you make this decision? Be specific! g. Report Cramer's V (or Cramer's phi) and interpret this value. h. What can the researcher conclude? 2. Using the data from the previous example, use SPSS to obtain the Chi-Square value and p-value. Note: you do not need to enter raw data, you may enter the cell frequencies from the table. a. Include a screen shot of the Data View screen after you have entered the data b. Include a screen shot of the Variable View screen after you have added Value Labels c. Include a screen shot of your Output.
