Question

Quizplus · Accepted Answer

The principle of randomness in public opinion polling refers to the idea that every individual in the population has a known and equal chance of being sampled. This helps to prevent sampling bias and ensures that the sample is representative of the population being studied. Option A is incorrect because every individual sampled does not necessarily decrease the risk of bias error if the sampling method is flawed. Option B refers to the concept of voluntary participation, which is related to sampling but not randomness. Option C may not be possible or practical in many cases due to constraints such as time and resources. Option E refers to the diversity of perspectives within the sample, which is important but not directly related to randomness.
