1 In a study of violent victimization of women and men Porce

1 In a study of violent victimization of women and men, Porcerelli et al. (A-11) collected information from 679 women and 345 men ages 18 to 64 years at several family-practice centers in the metropolitan Detroit area. Patients filled out a health history questionnaire that included a question about victimization. The following table shows the sample subjects cross-classified by gender and whether the subject self-identified as being “hit, kicked, punched, or otherwise hurt by someone within the past year.” Subjects answering yes to that question are classified “violently victimized.” Use logistic regression analysis to find the regression coefficients and the estimate of the odds ratio. Write an interpretation of your results.

Victimization Women Men Total

No victimization 611 308 919

Violently victimized 68 37 105

Total 679 345 1024

Solution

Thus,

Odds of Victimization to non-victimization = 105 / 919

= 0.114

To check if Women are more victimised the men,

Odds ratio = (68 /611) / (37/308)

= 0.926

Since, Odds ratio is less than 1, we can say that it is not true that women are violently victimised more than men.
