Selecting The Right Research Design

Selecting The Right Research Design

Great chess players know their next three moves in advance. A chess master can even know how the match might end in the first few moves. The master does so by knowing not only how the pieces can move, but also how they will move based on external factors. The player creates a plan based on all information available and how that information will factor into the game. Similarly, researchers must plan in advance to foresee obstacles that might trouble their research design.

For this Discussion, you will reflect on the information available to you from previous work in this course to create a research design for answering the three questions you have generated. You will further practice creating research designs by giving colleagues feedback on their own.
Reflect on the quantitative research questions on the Research Question Types Quiz Worksheet you completed for the Week 2 Discussion. You learned and recorded on your worksheet which research questions are descriptive, relational, or comparative.
Select a descriptive research question, a relational research question, and a comparative research question.
Consider an appropriate research design for each of your three selected questions.

Post and describe an appropriate research design for each of the three different research questions you identified from your Research Question Types Quiz Worksheet. Be sure to include your research questions as part of your discussion. Explain your reasoning for selecting the research design you chose for each of your research questions.
