This data set represents hypothetical data from a study that examined the relationship between infant attachment style as measured in infancy and education obtained when measured in adulthood. That is, the same participants had their attachment style measured as young children, and then researchers measured the participants’ level of education obtained many years later.
Here is some more information about the variables in this hypothetical data set:
• Number: The ID number of the participant
• Sex: Participants’ sex, with 1 = male and 2 = female
• Infant_Attachment: Participants’ infant attachment style, with 1 = secure, 2 = anxious, and 3 = avoidant
• Education: Participants’ level of education obtained, with 1 = high school, 2 = undergraduate, and 3 = graduate
Questions:
1) Briefly describe a research situation that would call for a chi-square analysis. Be sure to explain each variable and the possible values of each variable.
2a) Generate a cross table of Infant_Attachment and Education.
2b) From these results, which group attachment style seems to be most related with obtaining high levels of education?
3a) Conduct a chi-square test to see if Infant_Attachment and Education are independent from one another.
3b) Document the results of this test in APA style. Be sure to explicitly state whether or not the two variables are independent. Refer to How to Report a Chi-Square Test Result (APA) for guidance.
4a) Run the chi-square again, but this time add sex as a layer.
Paste output below (Read carefully: The best way to do this is to select “Copy Special” when copying from the SPSS output. Then select image as a format to copy. When pasting in Word, select Paste Special, choose a picture format, and then resize the image so it fits the screen):
4b) Based on these results, does the relationship between Infant_Attachment and Education hold for both males and females? How do you know?
