Quizplus · Accepted Answer

All three statements are correct regarding probability samples. A probability sample is based on the principle of random sampling, which ensures that every member of the population of interest has an equal chance of being selected for the sample. Therefore, the researcher can be sure of obtaining information from a representative cross-section of the population of interest. Sampling error can be computed, which provides an estimate of the extent to which the sample statistics differ from the true population parameters. The survey results can be projected to the total population based on the principles of probability sampling.
