Which sampling technique is generally followed when the population is finite?

Systematic sampling is generally used with a finite, listed population by choosing every kth element.

Area sampling divides a geographic region into areas and suits large, dispersed populations.

Purposive sampling picks units by the researcher's judgment and is a non-probability method.

None of the above is wrong because systematic sampling directly fits a finite population.

The sampling interval k equals the population size divided by the desired sample size.

A random start within the first interval keeps the systematic selection probability based.
