How to Calculate Sample Size
Before you decide on the exact number of individuals to include in
your survey, there are a few factors that you should take into
consideration. Here is an article that explains these factors in depth
and how to determine the best sample size for your survey, but you will find a basic rundown of the process below.
Factors to consider include:
- Objective of the Survey: If you are interested in using the results of your survey to make a big decision or you plan to project the results on a larger population, the sample size is critical. If, however, you are merely using the results to get a feel for a specific group’s preferences the size of your sample may not be as important.
- Diversity: How diverse is the population of individuals or groups you wish to survey? While similar respondents can typically be surveyed using a smaller sample size, surveys that require a more diverse population will receive more accurate results with a larger sample size.
- Accuracy: How critical is the accuracy of your survey results? Sample size and targeted audience can play a significant role in the accuracy of your survey. For example, if you are planning to use the results of your survey to make a large investment or make a decision that will affect a large population, the accuracy of your survey is likely extremely important and a larger sample size is essential.
- Rate of Response: In order to target the most effective sample size for your survey, you should first consider the number of respondents you will need as well as the willingness of your audience to participate in your survey. If you estimate that only 50% of your audience will respond, and you need at least 100 respondents for example, you will likely need to target a minimum of 200 individuals.
- Audience: Another factor that should be considered when it comes to how to calculate sample size is the audience itself. You wouldn’t want to target homeowners when surveying about the quality of local apartment life, for example. If you send out a survey that is targeted toward a specific audience that is qualified to provide accurate answers, your sample size may not need to be as large as it would be if you decided to survey random individuals in the area.
Once you have reviewed the above factors, it’s time to calculate your sample size. This sample size calculator is
an excellent free tool that is designed to help users determine the
most effective sample size based on the population to be studied and the
confidence level you wish to achieve. When combined with the data from
the factors above, the calculator can help you pinpoint a much more
accurate estimate of the size of your sample.
