Suppose that Dr. Rand goes to a college reunion and asks for volunteers to take a memory test. He identifies 4 groups: people who graduated in 1920-1925, in 1940-1945, in 1960-1965, and in 1980-1985. He then analyzes how these groups compare to each other on the tests. Dr. Rand's study is best considered to be an example of:

▸ an experiment

▸ a cross-sectional study

▸ a longitudinal study

▸ both a cross-sectional and a longitudinal study
