This means that every element in the population must be assigned to only one stratum, and there shouldn’t be any overlap of elements across the stratas. The population is first divided into homogeneous subpopulations, or stratas, that are mutually exclusive and collectively exhaustive.

SIMPLE RANDOM SAMPLING METHOD EXAMPLE SERIAL NUMBERS
After creating a random number table with the serial numbers of your target population, you may select specific columns/rows for your sample group according to your decided sample size. Random number tables, such as the one below ranging from 000-300, can also be used. Necessary commands must be input in regard to population size and required sample size. Then, chits are picked out of the container to select the sample group.ĭifferent market research tools are used by researchers to pick a sample group. This method involves all the serial numbers being written down on chits of paper and being put into a container that is properly mixed manually. After finding the total number of units/people within the population, the researcher must then assign serial numbers to each one of them.įor example, if the study is on the employees of an organization that has 300s employees, each one of them must be assigned a number as they are the population from which the sample must be drawn.Īfter the numbers have been assigned, there are a few common ways in which the required sample size can be drawn from the population: In order to use simple random sampling in a market research tool, a researcher must know the size of the population in order to ascertain the number of total units in the population. Simple random sampling is usually used for large populations, hence, it is important to ensure a sample size that is large enough to fittingly represent this population otherwise it will lead to increase in margin of error. In other words, this method of sampling ensures that the data extracted from the chosen sample group is reflective of what it would be for the target population as a whole.
This method of sampling is most apt for when the main objective of a study is for its findings to be generalizable for a whole population. Simple random sampling assigns numbers to everyone within the population, so that a sample group may be selected using processes that pick random numbers from the list. This means that when employed, simple random sampling gives everyone in the target population an equal and known probability of being selected as a respondent in the sample group. Simple random sampling is a sampling method used in market research studies that falls under the category of probability sampling.
