How Many Responses Do I Need For My Academic Survey?

You are conducting research for your academic paper, but you do not know how many respondents you need to have to validate your survey? We would like to make your job easier by explaining to you various methods for deciding how many answers are required for the successful survey. 

Let's see first what exactly survey research is. Survey research includes a larger number of respondents selected on the basis of a random sample to represent their population. This research is conducted through predefined questions that are numerically encoded. The problem that often arises in connection with this type of research is the number of responses necessary for the survey to be accurate.

In the selection process of the sample (sampling process) from some basic set, it is necessary to make sure that it is representative in order to avoid systemic errors. The representative sample is the one that is chosen on the basis of probability and is of sufficient size.

As for the number of respondents, an amateur conclusion is imposed: the more - the better. However, this does not have to be the case if you are testing the wrong people. So, first and foremost is to decide which your target group is. For this only, you need separate research.

Is 50 enough?

Many students wonder if 50 respondents from the representative group are enough to get you a good result. It depends on the subject of your inquiry. By convention, a minimum sample size of 30 is needed to do statistical research. 50 respondents should be enough for an exploratory or pilot study. For a qualitative case study, it is more important that your samples are well chosen. For example, respondents who differ in some way.

One thing you must not forget and that is the response rate which consequently affects the number of responses you will through your survey. For example, if you need 50 respondents and you expect 25% of the people asked to take your survey will actually respond, then you need to invite 200 people to take your survey.  If you need to calculate the number of people you need to invite to take your survey based on your expected response rate, you should divide the number of respondents you need with the expected percentage rate and then multiply that number with 100.


If you, for an example, want to research on some very popular topic you should have a good research sample, meaning more than 50 respondents. One more way you can conduct your survey includes multipliers. For instance, you can apply a multiplier of minimum five to determine the sample size. If you are having 30 questions in your survey multiply it with 5 and you will get the number 150; which means you should have a minimum of 150 responses. When we are talking about a good sample size regarding popular topics, researchers favor having a multiplier of 10. If your questionnaire includes 30 questions multiplier of 10 will determine 300 responses to be a good sample size.
