Random, systematic, convenient, cluster, and stratified sampling are the five types of sampling.
Simple random sampling.
Judgement (or Purposive) Sampling.
A sampling strategy in which each sample has an equal chance of being chosen is known as random sampling. A sample drawn at random is supposed to be a fair reflection of the entire population.
The random sampling approach is one in which every item in the population has an equal probability of being chosen for the sample. As a result, this method is also known as the chance sampling method.
In a statistical study, sampling procedures refer to how members of the population are chosen to participate in the research. If a sample isn't chosen at random, it'll almost certainly be prejudiced in some way, and the results won't be representative of the entire population.
