Various Methods of Survey Sampling

Survey sampling is just selecting or picking some members from a targeted population for a sample survey. The survey involves some types of questionnaire. It is important to understand that the science of survey has just changed some of the issues affecting the society and even the society at large. Therefore, if you need to conduct this survey sampling, make sure that you have a group of people who will be willing to participate in the survey.

The group of people who will participate in the survey is referred as a sample. Also, the process of determining the exact number of participants in a sample group is known as sampling. You need to know the best steps to consider when planning to conduct or have a sample for your survey. The first thing you need to do is defining your target population. For instance, if your survey objective is to know the effectiveness of a specific product, then your target population should be the customers who have used it.

Basic sampling techniques

Random sampling

Also, this method does not require a vast population because it will be impossible or difficult to identify each member of the population.

Systematic sampling

This is another method of survey sampling that is used instead of the random sampling. After the required sample has been calculated, then the sample is picked from a list of population members. Therefore, if the file that has been selected does not have any hidden order, then the sampling method is good. Most people prefer this method because of its simplicity. Lastly, it is crucial to understand that the systematic sampling is used to pick a specified number of records from a computer file.

Stratified sampling

It is essential to know how this procedure is done because it is somehow complicated, unlike other sampling methods. There is a stratum that is mainly a subset of the population that will share even one common characteristic. An excellent example of a stratum is a non-manager, manager or a female and a male. Therefore, this method is used when you find that one or more stratum in a given population has a low incidence just as the other stratum.…
