We present data for 20 men and women. In addition to measuring respondent’s sex (M = male, F = female), we also measured their home ownership status (O = own, R = rent), and fear of walking alone at night (Y = yes, N = no).

1. Construct a bivariate table of frequencies for sex and fear of walking alone at night. Which is the independent variable?
2. Calculate percentages for the table based on the independent variable. Describe the relationship between sex and fear of walking alone using the table. What sampling issues are involved here?
3. Use the data to construct a bivariate table to compare fear of walking alone at night between people who own their homes and those who rent. Treat home ownership as your independent variable.
