![]() Here, the researcher does not create clusters, but he/she narrows down the convenience sample by applying random sampling.įor example, a researcher wants to understand pet feeding habits among people living in the USA. But in this case, the researcher chooses the samples randomly at each stage. The concept of multistage random sampling technique is similar to multistage cluster sampling. Here we see that clusters are selected at various stages until the researcher narrows down to the sample required. He/she further chooses particular respondents from the selected cities to participate in research. The researcher does not interview all the residents of the city or town. And from these regions, he/she further narrows down his research by choosing specific cities and towns that represent the region. From these countries, he/she chooses the regions or states to survey. ![]() The researcher will first choose the countries of interest. It is practically impossible to collect data from every household. These groups are called clusters.įor example, a researcher wants to know the different eating habits in western Europe. The researcher divides the population into groups at various stages for better data collection, management, and interpretation. Multistage cluster sampling is a complex type of cluster sampling. Let’s take a look at these two approaches in detail. In market research, multistage sampling is the choosing of samples at stages and choosing smaller sampling units at every step. There are two types of multistage sampling – multistage cluster sampling and multistage random sampling. What are the types of multistage sampling? It does not need a complete list of all the members of the target population, dramatically reducing sample preparation cost.It decreases the issues faced during random sampling. The researcher mindfully chooses the audience.Finding the right survey sample becomes very convenient for researchers.Cost-effective and time-effective because this method helps cut down the population into smaller groups.It is useful while collecting primary data from a geographically dispersed population.It allows flexibility to the researchers to choose the sample carefully. Researchers can divide the population into groups without restrictions.Researchers can apply multistage sampling to make clusters and sub-clusters until the researcher reaches the desired size or type of group.It allows researchers to apply cluster or random sampling after determining the groups.Here are the top 8 benefits obtained from multistage sampling: What are the advantages of multistage sampling? The information collected from the samples is used to draw inferences from the population as a whole. It also keeps a tab on the cost of the research. ![]() Multiphase sampling reduces the time taken to research an area. Government bureaus use this method all the time to draw inferences from the population.To survey employees of a multinational company belonging to multiple locations in multiple countries.To gather student perceptions from students belonging to various colleges, studying different courses and located throughout the country.Applied to a multistage design where the population is too vast and researching every individual is impossible.Multistage sampling is applied mainly to these areas: LEARN ABOUT: Sampling Frame What are the applications of multistage sampling? Step four: Using some variation of probability sampling, choose the members of the sample group from the sub-groups.Step three: Repeat the second step if necessary.Do this from related, different discrete groups selected in the previous stage. Step two: Select a sampling frame of relevant separate sub-groups.The researcher allocates a number to every group and selects a small sample of relevant separate groups. Step one: Choose a sampling frame, considering the population of interest.There are four multistage steps to conduct multistage sampling: Select your respondents What are the steps to conduct multistage sampling? During this sampling method, significant clusters of the selected people are split into sub-groups at various stages to make it simpler for primary data collection. It is a complex form of cluster sampling, sometimes, also known as multistage cluster sampling. Definition: Multistage sampling is a sampling method that divides the population into groups (or clusters) for conducting research.
