SYA 4300 : METHODS OF SOCIAL RESEARCH Fall Semester 2011 Lab Homework #2 50 Points Due: Friday September 30, Midnight (11:59pm) Using an Index to Assess Opinion Towards Abortion in the GSS Would the items abrape , abhlth and abdefect be useful for constructing an index of attitudes toward abortion for the combined years 2000 and 2008? To answer this question, complete the following for the sample of respondents who answered all three questions during 2000 and 2008: 1. Assess the face validity of abrape , abhlth and abdefect . Use complete sentences in your response. 2. Report all possible bivariate relationships by showing the cross-tabulations among the three items. Are there sufficiently strong bivariate relations for creating an index? Explain your answer with reference to the numbers that you see in your tables. 3. Assess the robustness of the relationships between abhlth and abrape and abhlth and abdefect by evaluating a tri variate relationship among the three items. Do this by generating a table showing the percentage answering “yes” to abhlth for the four groups of respondents defined by their responses to abrape and abdefect . Are the relationships sufficiently robust for creating an index? Explain with reference to your results.
