Experimental vs. Nonexperimental Research Design

Describe the differences between an experimental, a quasi-experimental and a nonexperimental research design.

Make sure to include a detailed description demonstrating your understanding of these differences. Identify and describe two types of experimental, two types of quasi-experimental, and two types of non-experimental research designs making sure to include the benefits and limitations of each. Explain the importance of validity in quantitative research and the different types of validity. Describe and explain two ways you would control participant characteristics with examples and why this is important to conduct a quantitative research study. Additionally, describe and explain two threats to internal validity and why these threats are important considerations when conducting a quantitative research study.
