Toennäköisyysnäytteenoton
Toennäköisyysnäytteenotto, also known as probability sampling, is a fundamental concept in statistical survey design and research. It refers to a method of selecting a sample from a population where every member of the population has a known, non-zero chance of being included in the sample. This contrasts with non-probability sampling methods, where the selection is not based on random chance.
The core principle of probability sampling is to ensure that the sample is representative of the larger
Common types of probability sampling include simple random sampling, where each member has an equal chance
The primary advantage of probability sampling is its ability to support statistical inference. The known probabilities
