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.
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.

Consider this scenario:
You are a researcher investigating risk factors related to pancreatic cancer. In order to promote positive social change, it is important to collect a large enough sample size to justify making generalizations to their population out of people who have pancreatic cancer.
In this Discussion, reflect on the number of variables you plan to use and consider the impact that sample size has on generalizability.
Post your response based on the literature from your search: What should be the minimum sample size for this study related to pancreatic cancer in order to justify making generalizations from the sample to the population? What information would you need to know in order to use the Power Table to determine an appropriate sample size?
Further, explain the possible consequences of having too small of a sample size for this study.
