Random sampling
Random sampling is a fundamental method used in research and statistical analysis to select a subset of individuals or items from a larger population. This process is characterized by its randomness, which means that each member of the population has an equal and independent chance of being chosen for the sample. Random sampling is crucial for obtaining representative and unbiased data, allowing researchers to make valid inferences about the entire population based on the characteristics of the selected sample.
