simple random sample
Quick Summary
In statistics, sampling is the process of selecting a representative group from a larger population to gather information. This is done when surveying every member is impractical.
The most basic design is simple random sampling. In this method, every individual or item in the population has an equal chance of being chosen. This allows researchers to estimate the likelihood that their findings are due to chance and helps avoid bias. Other methods, like stratified or cluster sampling, are variations that build upon this principle to improve representativeness or efficiency.12
