The correct answer is C) To ensure their results are considered stable and trustworthy.
Sociologists use scientific methods of study in their investigations to ensure their results are considered stable and trustworthy.
Although sociology is a social science, the results of the investigations have to be measured to be valid. That is when scientific methods come into place. Sociologists need to do research based on valid sources, primary or secondary, examinations, and interviews in order to get the correct data that can be proved throughout experimentation. Then, provide facts, numbers, and statistics to make it valid and ensure their results are considered stable and trustworthy.
