Experimental Designs Introduction Selecting a research design to test your hypothesis is the next key step toward building a research plan. Whether it is an experimental design or an alternative design is a decision you must make based on your research topic. This week focuses on classic experimental designs available for quantitative research topics. There are several possible structures to an experimental design that you must choose from to generate the most useful, accurate data and to support your conclusions. This week, you will evaluate which of these methods may work best for your own research plan, and consider what types of threats to validity are present in each model. You will find that as you examine research designs over this week and next week, the most appropriate design choice for your research will be closely tied to the hypothesis with which you are working. Submit a 3- to 4-page draft of the first part of your research plan. Include the following elements in your draft: o Title o Introduction o Opening statement Background of study Problem statement Purpose of the study Research question(s) and hypotheses Theoretical framework Books o Creswell, J. W. (2009). Research design: Qualitative, quantitative, and mixed methods approaches (3rd ed.). Thousand Oaks, CA: Sage Publications. This textbook will be useful when writing your introduction Reynolds, P. D. (2007). A primer in theory construction. Boston: Pearson Education
