A researcher uses a computer to obtain a sample of city residents so each resident has an equal chance of being selected. Which sampling method is being used?

Judgment sampling involves selecting individuals based on the researcher’s subjective judgment rather than a random process. This method does not guarantee that each resident has an equal chance of being selected, potentially leading to biased results that do not accurately represent the population.

Convenience sampling refers to selecting individuals who are easiest to reach, such as those readily available or nearby. This method fails to provide equal chances for all residents to be selected and can result in a non-representative sample that overlooks diverse perspectives within the population.

Stratified sampling is a method where the population is divided into distinct subgroups (or strata) and random samples are taken from each stratum. While this technique aims to ensure representation of various segments of the population, it does not involve giving each individual an equal chance of selection across the entire population as simple random sampling does.
