Pop-->sample uses what concept?

• A. Probability.
• B. Causation.
• C. Intuition.
• D. Determinism.

Answer: (A)

Probability governs how we pick a sample from a population. When you draw a sample, you rely on random processes so each member of the population has a known chance of being included. This probabilistic basis lets you describe the sampling method with probability theory, quantify sampling error, and make inferences about population parameters from the sample with an associated level of uncertainty. Causation is about one variable causing another, which isn’t about how the sample is chosen. Intuition is informal judgment rather than a formal method. Determinism implies there’s no randomness, which doesn’t describe the idea of random sampling.
