Quizplus · Accepted Answer

The Answer is The distinguishing characteristic of probability sampling is that the researcher can specify,for each element of the population,the probability that it will be included in the sample.In nonprobability sampling there is no way to estimate the probability of each element being included in the sample.Probability sampling is much more likely than is nonprobability sampling to lead to a representative sample of the population.Two types of probability samples are simple random samples and stratified random samples.Nonprobability samples are often called convenience samples because they comprise elements (people)who are available and willing to participate.
