What is the difference between quota and stratified sampling?Watch
Quota sampling- A non-probability sampling technique where the sample has the same proportions of individuals as the entire population with respect to characteristics.
Stratified sampling- Where the researcher divides the entire population into different subgroups, then randomly selects the final subjects proportionally from the different strata.
But I am failing to see the difference.
Essentially, quota sampling is the faster, cheaper, but less reliable method, and can be influenced by the personal bias of whoever is doing the sampling.
