Sampling methods شرح مبسط

sampling is the process of using a subset of a population to represent the whole population. There are two major types of sampling methods: probability and non-probability sampling. Probability sampling, also known as random sampling, is a kind of sample selection where randomization is used instead of deliberate choice. Each member of the population has a known, non-zero chance of being selected. Non-probability sampling techniques are where the researcher deliberately picks items or individuals for the sample based on non-random factors such as convenience, geographic availability, or costs.
