Focus on a specific time period, population, or geographic area.Use these criteria to limit your topic and make it more specific. This will give you a smaller population to work with so your conclusions will be more reliable. It also makes your study more workable.[4]
For example, you might be interested in a national issue, but studying the national population would be unworkable. Instead, you might focus on the impact of that issue on a smaller population, such as the people in your city.
If you go too far and end up making your topic too narrow, simply reverse the process.
