B3. This exercise involves producing risk index statistics, again using the dataset Polit2SetB. Run the SPSS Crosstabs procedure, using poverty status (poverty) as the risk exposure variable—i.e., inserting it as the row variable. Then find Variable #43 toward the end of the variable list (health), which is a health status variable that dichotomized answers to a question that asked women to self-rate their health. Those who said they were in good, very good, or excellent health are coded 1, while those who said they were in fair or poor health were coded 0.

Use health as the column variable in the Crosstabs. Click on the Cells pushbutton, and click on Row under Percentages. Then hit Continue and click the pushbutton for Statistics. On the right-hand side, click on the option for Risk, then click Continue and OK. Then answer these questions:

(a) What is the absolute risk of being in fair-topoor health for women below the poverty level and above the poverty level?

(b) What is the odds ratio for the effect of exposure to poverty (versus nonexposure) on the outcome of fair-poor health?

(c) What is the relative risk of exposure to poverty (versus nonexposure) on the outcome ?
