Explanation: 

Detailed explanation-1: -Systematic sampling is another technique often used when conducting a survey. Under this design we may sample every tenth person from the population. Often time’s systematic sampling will be called random systematic sampling. This implies that a random starting point was used and then every tenth person was sampled.

Detailed explanation-2: -Systematic sampling, also called nth name selection technique, is often used instead of random sampling due to its simpler process. After the sample is collected, every nth member within the population is recorded within the sample.

Detailed explanation-3: -Systematic Sampling In systematic sampling, every Nth name is selected from the list of the members of the target population. For instance, the sample will include the participants listed in every 10th from the list. That means the 10th, 20th, 30th and so on will be selected to become the members of the sample group.

Detailed explanation-4: -There are four primary, random (probability) sampling methods – simple random sampling, systematic sampling, stratified sampling, and cluster sampling.
