Explanation:

Dr. Miller selected participants, gave them a survey to collect data on cell - phone use and short - term memory (recall of world events). This is characteristic of an experiment as it involves manipulation (asking specific questions) and data collection to test a hypothesis (cell phone usage affects short - term memory). A correlation would just look at the relationship between variables without manipulation, a meta - analysis combines results from multiple studies, and a case study focuses on an in - depth analysis of a single case or a small group in a more qualitative way.
