Chapter 5 Question B7

Using the variable poverty as the row variable in a Crosstabulation analysis, calculate RRs and Ors between the women’s poverty status and four to five other dichotomous outcomes of your choosing in the Polit2SetB dataset. Create a table presenting the results, and write a brief paragraph summarizing key findings. Be sure that your table and discussion include information about CIs.

Chapter 6 Question B6

Run independent groups t test for three outcomes in the Polit2SetC dataset: cesd and the two subscale score variables for the SF-12 scale that we have used in earlier chapters for physical and mental health (sf12phys and sf12ment). In these t tests, you will be testing the null hypotheses that women who do not have a high school education have the same scores on these three health outcomes as women who have a diploma or GED certificate. The relevant variable in which code 1 represents no high school credential, and code 2 represents a diploma or GED. (Code 3 and 4, corresponding to Associates and Bachelor’s degree, will be ignored in this analysis. Only 34 women in the sample had either of these degrees.) In the Independent-Samples T Test Variables, insert the three outcome variables in the list of Test Variables and educatn as the Grouping Variable. For defining the grouping variable, enter code 1 for Group 1 and 2 for Group 2. When you have run these analyses, create a table to represent your results, using Table 6.3 as a model. Be sure to include effect size information, which you will need to compute manually. Then write a paragraph summarizing the results.
