Final answer:
In selecting a study to answer a research question, consider the question type and appropriate methodology, such as surveys for gathering opinions and case studies for observing behavior.
Step-by-step explanation:
When choosing a study to answer your research question, it is important to consider the type of question you are asking and the methodology that would be most appropriate.
For example, if you want to gather opinions or information about behavior, a survey would be a good choice. Survey questions that are easy to answer and generate useful information include 'what' and 'who' questions. On the other hand, if you want to observe and draw conclusions about behavior, a case study would be more suitable.
