DATASET CREATION

Using the measure for clinical practice included in your exam packet, A. Create an SPSS data file for the first 20 items of your assigned clinical measure (hat you were given in class. Completing all fields in variable view. B. Be sure to also include all demographic variables appropriate for the population for which the clinical measure was designed. C. Email the data file you create. D. E-mail me the data file. so review it for errors before you send it. II. Preparing Datasets for Analysis (5 points) Using the Survey of Urban Americans 2012 data file and using SPSS: A. Randomly select 20% of the 1974 cases in the data file B. Create a “screen shot” of the Data View Screen which displays some of the cases that were both included and excluded. C. Using the 20% of cases conduct the statistical tests you would use for the data cleaning process on 2 demographic, 1 substance abuse and 1 criminal justice related variable. D. Write a report of the results of your analysis, using “copy & paste” to including the relevant SPSS output. III) Computing & Interpreting Measures of Central Tendency and Variability A. Using the Well-Being data file; report the appropriate measures of central tendency and variability for the following variables: financial status and depression. Explain why they are the appropriate measures to report. B. Using the PTSD data file; cut and paste below histograms with the normal curve for the variable post-traumatic stress disorder by gender. What do the graphs tell you about the distribution for females and males? Be explicit. Discuss how you would you use the results to inform your practice with the participants in this data set. IV) Assessing for Normal Distribution & Correcting Skewed Distributions A. Using the Survey of Urban Americans data file with the 20% of cases randomly selected, comment on the distribution for subjective class identification. Is this variable normally distributed? Be both explicit and comprehensive in your discussion. Report findings from the appropriate output to support your statements. B. Using the PTSD data file, report the 95% confidence interval for post-traumatic stress disorder. Explain what this means. What is the corresponding alpha? Cut and paste the appropriate SPSS output below. C. Using the Survey of Urban Americans data file with the 20% of cases randomly selected, find a variable that is not normally distributed and correct its distribution. Discuss how you identified the variable as not normally distributed an, what you did to correct the variable’s distribution and the outcome of your efforts. Did the distribution significantly improve? Given the outcome would you use the original or the transformed version of the variable? Why or why not?I V) One vs. two-tailed Hypothesis & Testing for Group Differences A. Using the Job Satisfaction database select two variables, clearly identifying which is the independent and which is the dependent variable, develop and state a one-tailed hypotheses using the variables you’ve selected and run the analysis to text that hypothesis. What do the results tell you? Discuss how you, would use the results to inform social work practice and policy. B. Using the Anxiety data, conduct an analysis of the pre and post-test data. Describe what you did and the results of your analysis. Report findings from the appropriate output to support your statements. Discuss how you would you use the results to inform your practice with the participants in this data set. C. Predict the correlation between income and depression and state a null and a one tailed research hypothesis predicting the relationship between them. Using the Welfare data file, test these predictions. Report the results of your analysis using relevant SPSS output. Discuss how you would you use the results to inform your practice with the participants in this data set
