A population is the entire group about which we want to know information. A sample is a smaller group from which we actually collect data. We cannot always measure an entire population, so we use samples to make predictions and inferences. article https://www.khanacademy.org/math/statistics-probability/designing-studies/sampling-methods-stats/a/sampling-methods-review 2024-02-20T13:25:57.751434196Z Sampling methods review article https://www.khanacademy.org/math/statistics-probability/designing-studies/sampling-methods-stats/a/worksheet-samples-and-surveys 2021-04-29T07:59:30Z Samples and surveys article https://www.khanacademy.org/math/strengthened-shs-general-math/x24dc5a0902f75de5:third-quarter/x24dc5a0902f75de5:sampling/a/gtp--sat-math--article--data-collection-and-conclusions--lesson 2021-04-29T07:49:32Z Data collection and conclusions | Lesson article https://www.khanacademy.org/math/ap-statistics/gathering-data-ap/sampling-observational-studies/e/identifying-population-sample 2024-01-03T20:09:37.922655717Z Identify the population and sample Practice identifying the population and sample in a statistical study.
