Probability sampling ppt. It then outlines several specific probability sampling techniques: random sampling, systematic random sampling, stratified random 1. It begins by explaining that probability sampling selects subjects with a known probability, giving every unit in the population an equal chance of being selected. This document provides an overview of different sampling methods, including probability and non-probability sampling. Variations. This document discusses different probability sampling techniques: simple random sampling, systematic sampling, stratified sampling, and cluster sampling. It aims to result in a sample that accurately represents the larger population. Some Definitions. Last modified: 4-8-2015. 3.
