Answer 1

The study design used when a researcher randomly samples a large number of individuals to collect information about their multivitamin use is typically a **cross-sectional study**. In this type of study, data is collected at a single point in time from a sample that is representative of a larger population. By randomly sampling individuals, the researcher aims to gather information about their multivitamin use and potentially identify patterns or associations within the data.
