Many research studies require specific groups of interest to make decisions based on their findings. This group of interest is known as a sample. Sampling is a method deployed to select survey respondents. For example: If you are interested in the average time a person between the age of 30-35 takes to recover from a specific ailment after consuming a particular type of medication, the population of interest is all persons between 30-35 year-olds with that ailment using that medication. Select your respondents The population of interest is not limited to the human population only. It is a group of aspects that have something in common. It can be objects, animals, measurements, etc. having many characteristics within a group. For example, a medical study examines the spread of a specific disease in street dogs in a city. Here, street dogs belonging to that city are the population of interest. This population of interest or sample represents the entire population you want to conclude. Sampling is a powerful technique of collecting opinions from a wide range of people, chosen from a particular group, with the effort to know more about an entire group in general. Deciding upon a suitable sample from your population of interest depends on several key factors:
For any research population to be practical, it is imperative to select the population of interest that is truly representative of the whole population.
Now that you understand you can’t survey the entire population of interest due to various factors, you must adopt one of the best-suited sample selection methodologies for your research study. There are two methodologies you can apply: Probability sampling and Non-probability sampling. Probability sampling means selecting the sample based on the theory of probability. The sample includes everyone, with all having an equal chance of being selected. There is no bias whatsoever in this type of sample. Every person in the population has an opportunity to be a part of the research. What are the four types of probability sampling?
Non Probability sampling to determine the population of interest:The non-probability sampling method uses the researcher’s preference regarding selecting a sample. This method of sampling is derived mostly based on the researcher’s ability to access to this sample. Here the members of the population do not have an equal chance of being a part of the sample. What are the four types of Non-probability sampling?
What are the advantages of sampling in a population of interest?In most cases, out of the total population of interest, insights can be only gathered from your pre-defined samples. Here are the top nine advantages:
