• It is representative of the population

• It is incomplete

What is the principle of statistical regularity?

• Large samples always yield inaccurate results

• A randomly selected sample represents the population

• Sampling should not be used in research

• Only small samples provide reliable data

What is the first step in the sampling process?

What is the key feature of probability sampling?

• The researcher chooses the sample
