What term refers to the entire group of individuals a researcher wishes to study?

• A. Sample
• B. Population
• C. Random Sampling
• D. Sampling Error

Answer: (B)

The main concept is population: the entire group of individuals a researcher wishes to study. This defines who the study’s findings are meant to apply to. For example, if you want to understand sleep quality among all full‑time college students, the population is every full‑time college student, not just those you happen to sample. Because measuring everyone is usually impractical, data are collected from a sample, a subset of that population, chosen through a sampling method. Random sampling is one approach that gives each member of the population an equal chance of being included, helping the sample reflect the population. Sampling error is the natural difference that arises between the sample results and the true population characteristics due to the randomness of who ends up in the sample.
