what is sampling techniques in research

Sampling techniques in research refer to the methods used to select a subset of individuals from a larger population to make inferences about the whole population. There are two primary types of sampling methods: probability sampling and non-probability sampling. Probability sampling involves random selection, allowing for strong statistical inferences about the whole group, while non-probability sampling involves non-random selection based on convenience or other criteria, allowing for easy data collection. Some common non-probability sampling techniques include convenience sampling, judgmental sampling, and snowball sampling. It is essential to carefully select a sample that is representative of the group as a whole to draw valid conclusions from the results
