Using IBM SPSS Statistics textbook.
•    Review the video tutorial for an overview of chi-square analyses in SPSS.
•    Download and open the Attachment SPSS dataset.

An overview of the dataset:

This dataset 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 dataset:

•    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.

Type your answer below:

2a) Generate a cross table of Infant_Attachment and Education.

Paste your output below:

2b) From these results, which group attachment style seems to be most related with obtaining high levels of education?

Type your answer below:

3a) Conduct a chi-square test to see if Infant_Attachment and Education are independent from one another.

Paste your output below:

3b) Write up the results of this test in APA style. Be sure to explicitly state whether or not the two variables are independent. Use the

“Chi-square tests of independence” section of this website for guidance.

Type your answer below:

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?
