Quizplus · Accepted Answer

Xiao is using a cross-sectional research design because he is gathering data from different age groups at one point in time to compare their calorie consumption. A continuous research design would involve tracking one group of individuals over time to see changes in their calorie consumption, a sequential research design would involve studying different age groups over time, and a longitudinal research design would involve studying one group of individuals over a long period of time to see changes in their calorie consumption.
