Quiz 5 - Quantitative Analysis?

**This quiz is an exercise and will be graded for completion, not accuracy.

1. Search for the variable "nosmoke" which is a question about smoking in public places. What was the exact survey question that was asked to respondents, and what possible answers could respondents give (ignore those that didn't answer and those that didn't apply)?

2. In what year(s) was this question about smoking in public places asked? How many respondents total answered this survey question?

3. The bar chart below represents the variable EDUC, which measures respondent's education level. It has been recoded into categories representing degrees. How would you describe this distribution in words (in a short paragraph)?

4. What is the level of measurement for the recoded variable in question 3? How do you know?

5. Are these categories mutually exclusive? Why or why not?

6. Are these categories exhaustive? Why or why not?

7. Construct a frequency distribution for the respondent's family income level. Use the "suggested recode" from the list of variables provided on Research Assignment 2. Paste it here from the data analysis website (you may have to take a screenshot using ctrl-prt scr and crop out the table in Paint or another image editing app).

8. Also, paste a bar chart for respondent's family income level. (You may have to right click on the chart, and select "save image as..." before inserting the file into word.)

9. The contingency table below analyzes the variable RELITEN (strength of religious affiliation) and ABANY (whether or not the respondent believes a woman has a right to a legal abortion for any reason). Which is the independent variable in this table?

10. What is the null hypothesis for this relationship?

11. How would you describe this 2-variable relationship in words based on the contingency table above? (Hint: compare the interpretation of percentages across the rows to see the effect of X.)

12. If this sample analysis has a p-value of .00014, is the null hypothesis supported or refuted by the data? What would your conclusion be?

13. If SPANKING is the dependent variable, how would you expect it to be affected by people's political views? In other words, make a hypothesis about how people's opinion of spanking will differ by their political views (liberal, moderate, or conservative).

14. Construct a contingency table for the variables SPANKING and POLVIEWS. Use the "suggested recode" of POLVIEWS from the list of variables provided on Research Assignment 2. Paste the table here from the data analysis website.

15. Was your hypothesis supported from the data? Why or why not?
