c. Random sampling

Rendom sampling is a fundimental method used in statistic and research to select a subset of indivduals or items from a larger population for the purpose of makeing inferences or drawing conclusions about the entire population. The key characteristic of random sampling are that every member of the population has an equal and independant chance of been selected. This ensure that the sample is representive of the population, reduce bias and increase the generalizability of the findings.

Rendom sampling can take various forms, such as simple random sampling, where each member have an equal chance of selection; stratifyed sampling, where the population is divided into subgroups and samples are randomly drawn from each subgroup; and systematic sampling, where every nth member is selected after an initial rendom start. Rendom sampling are crucial in scientific research, polling, quality control, and various fields where accurate and unbaised information about a population is need.

In sumary, rendom sampling are a vital technique that help researchers obtain valid and reliabe results by ensure that the selected sample is a fair representation of the entire population.
