What does the term 'randomized survey' imply about the selection of participants?

The term 'randomized survey' indicates that every participant has an equal chance of being selected to participate in the survey. This method ensures that the sample is representative of the larger population, which helps to reduce bias and increases the reliability of the results. By using random selection, researchers can generalize findings to the broader population with greater confidence, as each individual has the same probability of being chosen, regardless of any characteristics they may possess. This approach is essential in achieving the goal of obtaining an unbiased view of the population being studied. Such randomization contrasts with other methods that might involve criteria-based selection or voluntary participation, which could skew the findings toward a particular demographic or opinion.
