Donald T. Campbell is considered one of the most important contributors to the development of quasi-experimental design. He developed the concept of "quasi-experiment" to describe studies that lack full experimental control but still allow researchers to make causal inferences. He also proposed several techniques to enhance the validity of quasi-experimental designs, such as regression discontinuity and matching. While the other individuals listed have made significant contributions to statistics and research design, they are not specifically known for their work on quasi-experimental design.
