Why is random sampling important in research?

Random sampling is crucial in research because it ensures that every member of the population has an equal chance of being selected to participate in the study. This method fosters a representative sample, which is essential for drawing valid inferences about the entire population. By reducing selection bias, random sampling helps to ensure that the findings of the research can be generalized beyond just the individuals included in the sample. If certain individuals have a higher probability of being selected, the results could be skewed and not reflective of the whole population. Therefore, option B highlights the significance of random sampling in maintaining the integrity and validity of the research outcomes.
