Figure:
Suppose a researcher wishes to use stratified random sampling to select a representative sample of 100 people from a population that has the following characteristics:
-Dual-income couples now outnumber those with single incomes,and this has led researchers to examine how the demands of maintaining dual careers affect relationships.The researchers found that among dual-career couples there was a positive correlation such that couples who spent greater amounts of time together found their relationship more satisfactory.Presume that this finding is a reliable one.What mediating variables would you propose to explain why there is a positive correlation between the time dual-career couples spend together and their degree of satisfaction with their relationship?
