Quizplus · Accepted Answer

When comparing attitudes of 70-year-olds today with those from 10 years ago, cohort (the group of people born around the same time) and time of measurement (the period when the attitudes are measured) are confounded. This is because the two groups of 70-year-olds belong to different cohorts and are measured at different times.
