In the first part of the project you will use the appropriate technique to use for each of the following questions.
· Is there a significant difference in the mean crime rate for Southern states and the mean crime rate for Northern states? Use the original crime rates.
· Is there a significant change in crime rates over the ten years between the first and second data collections?
· Was there a significant correlation between crime rate and police expenditures at the time of the first collection of data? To determine this, perform a simple linear regression for these variables including a scatterplot, r, r2, interpretation of r2 in the context of the problem, determine if slope is significant, and state what slope indicates in the context of the problem.
· Was there a significant correlation between crime rate and police expenditures ten years later? This should be answered using the same guidelines as the previous question.
Expectations:
• For each question you will determine the appropriate method of analysis and apply it with SPSS. All relevant output should be included in proper APA format.
• Your narrative should include the research question being addressed, the analysis method used to address it, the interpretation of the statistics, and references to tables and figures as appropriate.
Material to submit
• Your finished work must be a Word document in APA format. Please include a cover page. A reference page will not be necessary.
• Each of the questions give above should be addressed in its own section.
• Include the syntax from each analysis in an appendix. All the syntax can be combined into one appendix.
