Give example
In probability sampling, every member of the population has a known, non-zero chance of being selected in the sample. This approach allows for more generalizable results. Common methods include:
Simple Random Sampling: Each member of the population has an equal chance of being selected. This is often accomplished using random number generators.
Stratified Sampling: The population is divided into subgroups (or "strata"), and samples are taken from each stratum. This ensures that the sample is representative across all subgroups.
Cluster Sampling: The population is divided into clusters, often geographically, and a random sample of clusters is chosen. Then, all members from these selected clusters are surveyed.
Systematic Sampling: Every nth member from a list is selected, following a random start.
