A random sample size can be a very tiny percent of the population size and still have a small margin of sample error.

Question

Quizplus · Accepted Answer

A random sample size with a small margin of error can be achieved by using appropriate sampling techniques, such as probability sampling and stratified sampling, and by ensuring that the sample is representative of the population. A larger sample size usually results in a smaller margin of error, but a tiny sample can still have a small margin of error if it is well-designed and representative.
