There are several key aspects that go into a good research question. Based on several resources I have viewed, here are two characteristics that stood out to me as important:

1- Be specific, focused, and clear
Laurier library’s video recommends having a concise question that is not vaguely worded or broad in scope (Laurier Library, 2017). If your question is specific and clear, it can effectively address the issue, making it easier to find pertinent information regarding your topic.
2- Be relevant
According to McCombe’s blog post, a good research question should be relevant to your field of study. A relevant question should address a challenge or issue within your topic while also attempting to add new or additional information for others to consider (McCombes, 2022).
