An Overview of the Data Set
This data set represents hypothetical data from a study that examined the relationship between infant-attachment style as measured in infancy and education as 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 participant’s ID number
• Sex: The participant’s sex, with 1 = male and 2 = female
• Infant_Attachment: The participant’s infant-attachment style, with 1 = secure, 2 = anxious, and 3 = avoidant
• Education: The participant’s level of education obtained, with 1 = high school, 2 = undergraduate, and 3 = graduate
Questions
1) Briefly describe a research situation that would require a chi-square analysis. Be sure to explain each variable and the possible values of each variable.
[Insert your answer.]
2a) Generate a cross table of Infant_Attachment and Education.
[Paste your output.]
2b) From these results, which group-attachment style seems most related to obtaining high levels of education?
[Insert your answer.]
3a) Conduct a chi-square test to see if Infant_Attachment and Education are independent of one another.
[Paste your output.]
3b) Document the results of this test in APA style. Be sure to explicitly state whether the two variables are independent. Refer to How to Report a Chi-Square Test Result (APA) for guidance.
[Insert your answer.]
4a) Run the chi-square again, but this time, add sex as a layer.
[Paste your output.]
4b) Based on these results, does the relationship between Infant_Attachment and Education hold for both males and females? How do you know?
[Insert your answer.]
