Question

Quizplus · Accepted Answer

Dr. Itis is most likely to use a cross-sectional research design as he is gathering data from two different age groups at the same time. A cross-sectional design is used to compare different groups at a single point in time. A longitudinal design would require Dr. Itis to follow the same individuals over time, which could be difficult with a large age gap. A time-lag design would measure the same individuals at different points in time, but this does not fit Dr. Itis's intentions to gather data from two different age groups. A sequential design combines cross-sectional and longitudinal designs, which could also be a possibility, but based on the given information a cross-sectional design is the most appropriate choice.
