Measures of Association
Note: The following instructions are written to help you complete the assignment. (However, they are still not enough to replace the entire lecture. If you missed the lecture, you would probablly have many problems understanding the instructions. If you missed the lecture, try to complete the assignment as much as you can before you come to class and ask the instructors some specific questions.) Reading the required reading may also help you complete the assignment.
Use SPSS and complete the following (No manual calculations are required):
Use the data below and analyze the relationship between support for sexual equality and education level.

Education: 1. H 2. L
Gender: 1. Male 2. Female
a. State the null hypothesis. (Hint: This is just a statement. No calculations are involved. Later, you will see if the null hypothesis is rejected based on the significance level.)
b. State the directional hypothesis. (Hint: You just have to guess what relationship you expect between education and support.)
Create the dataset and perform a bivariate crosstab next.
(Hint: The dependent variable is Support. The independent variable is Education. Check the summary table under Exam 3 online. You find that Somer's d instead of Lambda is the correct statistic. AnalyzeDescriptivesCrosstab. Click Cell option and choose Column%. Click Statistics option and choose Somer's d.)
*Visit the course web page online and find an example of SPSS output:
c. What is the significance and the confidence level? Highlight the value for significance and answer the question. [Hint: Look at the last column in the statistics table where the label of the column includes the word "sig". Confidence level=(1the significance level) Use the second row, where the dependent variable is "support."]
d. What is the strength? Highlight the value and answer the question. (Hint: Look at the first column under the "Value".)
e. What is the direction? Underline the value and answer the question. (Hint: If the value of Somer's d is positive, the relationship is positive. If the value is negative, the relationship is negative. Remember that the sign may change, if the coding of variable is changed.)
f. Write a substantive interpretation using column% next to the crosstab. (Hint: Make sure to choose a row and compare the percentages horizontally.)
Second, add the gender variable as a control variable and find out if the original relationship remains the same.
a. What is the significance level for each group? What is the confidence level for each group? Highlight the values.
b. What is the strength for each group? Highlight the value and answer the question.
c. What is the direction for each group? Underline the value and answer the question.
e. What is your conclusion? Does the bivariate relationship that you saw earlier between support and education remain the same for both males and females? Do the results support the directional hypothesis that you came up with?
Copy and paste the SPSS output tables in a Word file. Make sure that the tables are organized well. (You can double click the tables and edit them. You can copy and paste the tables using the “paste as objects” function. You can shrink the tables, if they are too large.)
