|
All members of the target population have an equal chance of being selected.
|
|
|
Every nth member of a target population is selected to be in a sample.
|
|
|
The composition of the sample reflects the proportions of people in certain sub-groups (strata) within the target population / wider population.
|
|
|
The researcher selects anyone who happens to be willing and available at the time of their study
|
|
|
Involves participants selecting themselves to be a part of the sample.

Detailed explanation-1: -Systematic sampling is a probability sampling method for obtaining a representative sample from a population. To use this method, researchers start at a random point and then select subjects at regular intervals of every nth member of the population.
Detailed explanation-2: -Systematic sampling is when a researcher selects every nth person on the sampling frame to be part of the sample. The nth number is selected by dividing the target population size (the number in the sampling frame) by the desired sample size.
Detailed explanation-3: -Systematic sampling is a probability sampling method where researchers select members of the population at a regular interval – for example, by selecting every 15th person on a list of the population. If the population is in a random order, this can imitate the benefits of simple random sampling.
Detailed explanation-4: -Systematic sampling is a type of probability sampling method in which sample members from a larger population are selected according to a random starting point but with a fixed, periodic interval. This interval, called the sampling interval, is calculated by dividing the population size by the desired sample size.
Detailed explanation-5: -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.
