Dr. Samuelson is conducting a longitudinal study. In a longitudinal study, the same group of subjects is observed or assessed over an extended period to track changes or developments. In this case, Dr. Samuelson is planning to follow individuals of different age groups (20-, 40-, 60-, and 80-year-olds) over a period of 10 years to study the impact of social media on their friendships. This design allows for the examination of changes within each age group over time.
