Other Survey Research Political Polls Television Viewing Attitudes Marketing Survey Designs Longitudinal Designs Collection of Data over time and at specified points. Trend and cohort studies use different random samples each time to represent the group. If individual changes have occurred, the researcher cannot identify the individuals who have changed. After the sample is identified, the same individuals are sampled at each point. The researcher is able to identify the source of any change or effect.
Panel studies are generally short in duration.
