Arrange to interview two married couples, one younger and one older. Prepare a response form listing five product categories – groceries, furniture, appliances, holidays and cars – and ask each spouse to indicate, without consulting the other, whether purchases in each category are made by joint or unilateral decisions and to indicate whether the unilateral decisions are made by the husband or the wife.

Compare each couples’ responses for agreement between husbands and wives relative to who makes the decisions and compare both couples’ overall responses for differences relative to the number of joint versus unilateral decisions. Report your findings and conclusions.
