Part II: SPSS Application

These questions require the use of SPSS. Remember you must submit all of your work within this word document. You will need to take a screen shot of your data view if necessary, or copy and paste your output into the spaces below. Remember to report the exact p value provided by SPSS output - simply reporting p<.05 or p>.05 is not acceptable (unless SPSS output states p=.000 - in that case you can report p<.001).

Research Scenario: A developmental psychologist is studying whether attachment can be improved upon by providing a parent training course. He has 10 parents who are seeking services to improve their children's attachment to them. He uses a measure of which higher scores indicate more secure attachments to caregivers and gave it to them before and after the 4 week parent training course. The attachment scores data are presented below for Before and After the parent training course. Assume the data are normally distributed. Did the parent training course improve attachment?
