What is random selection?

Random selection is a method that guarantees every individual in a population has an equal chance of being selected for a study or survey. This impartial approach minimizes bias and ensures that the sample is representative of the larger population, making the findings more generalizable. By ensuring that each member of the population has the same opportunity to be included, it allows researchers to draw more reliable conclusions from their studies.

Other approaches mentioned, such as excluding certain demographics or selecting participants based on specific criteria, do not align with the principles of random selection. These methods can introduce bias and influence the results in ways that random selection seeks to avoid. Similarly, displaying survey results is a different process altogether and does not pertain to the selection of participants for a study. This emphasizes the importance of random selection in achieving fair and unbiased research outcomes.
