Identify the type of sampling used (random, systematic, convenience, stratified, or cluster sampling) in the situation described below. A researcher selects every 717 th social security number and surveys the corresponding person.

Sampling is a technique that seeks to extract a part of the elements that make up the population that we are going to study, so that the distribution of the sample is similar to that of the population, for this reason randomized procedures are usually used.

Systematic sampling is a procedure that requires that the elements of the population be numbered (for example the social security number), then a single number is chosen randomly and from this, with a constant period or interval, the other objects are selected of the sample (for example every 717 numbers)

Answer: the situation describes a systematic sampling
