Simple random sampling is a method used to cull a smaller sample size from a larger population and use it to research and make. Random sampling is one of the most popular types of random or probability it is advisable to use the first method but if the population has many members.

Although there are distinct advantages to using a simple random sample in research, it has inherent drawbacks. These disadvantages include the time needed.

Systematic sampling is a random sampling technique which is frequently chosen by researchers for its simplicity and its periodic quality.
