populationrepresentative
Population representativeness refers to the degree to which a sample or dataset reflects the characteristics of the broader population from which it is drawn. A representative sample supports generalizing findings, estimating population parameters, and informing policy decisions. The concept contrasts with convenience samples or biased datasets that over- or under-sample certain groups.
Achieving representativeness typically involves probability-based sampling methods, such as simple random sampling, systematic sampling, stratified sampling,
Limitations include nonresponse bias, undercoverage, measurement error, and time lags between data collection and the current
In reporting, researchers assess and document the sampling design, response rates, weighting schemes, and the degree
