Probability Sampling

Probability sampling is a method used in research where every individual in a population has a known, non-zero chance of being selected. This technique ensures that the sample accurately represents the entire population, reducing bias. Examples include random sampling, where each person has an equal chance, or stratified sampling, where the population is divided into groups and members are randomly chosen from each. This approach allows researchers to make valid generalizations from the sample to the larger population, improving the reliability and credibility of the study’s findings.
