Cross-sectional design would be the most appropriate method for Dr. Jones to use as it involves comparing different age groups at the same time. Dr. Jones can easily compare the TV watching habits of different age groups by selecting a sample of ten-year olds, twelve-year olds, and fourteen-year olds and then collecting data on their TV watching habits. Other designs such as longitudinal or pretest-posttest experimental would require more time and resources to track changes in TV watching habits over time or manipulate variables to test a hypothesis. A sequential design involves a combination of cross-sectional and longitudinal designs and is not necessary in this case.
