Size Posted byFluidSurveys Team July 8, 2014 Categories: How-To Article, Collecting Data, Research Design, Best Practices, Effective Sampling Calculating the right sample size is crucial to gaining accurate information! In fact, your survey’s http://fluidsurveys.com/university/calculating-right-survey-sample-size/ confidence level and margin of error almost solely depends on the number of http://www.polarismr.com/help-center/stat-calculator-margin-of-error/ responses you received. That’s why FluidSurveys designed its very own Survey Sample Size Calculator. But before you check it out, I wanted to give you a quick look at how your sample size can affect your results. Explaining Confidence Levels and Margin of Errors The first thing to understand is the margin of difference between confidence levels and margins of error. Simply put, a confidence level describes how sure you can be that your results are accurate, whereas the margin of error shows the range the survey results would fall between if our confidence level held true. A standard survey will usually have a confidence level of 95% and margin of error of 5%. Here is an example margin of error of a confidence level and margin of error at work. Let’s say we own a magazine with 1000 subscribers and we want to measure their satisfaction. After plugging in our information in the Survey Sample Size Calculator, we know that a sample size of 278 people gives us a confidence level of 95% with a margin of error of 5%. Our 95% confidence level states that 19 out of 20 times we conduct this survey our results would land within our margin of error. Our 5% margin of error says that if we surveyed all 1000 subscribers, the results could differ with a score of minus 5% or plus 5% from its original score. For the purpose of this example, let’s say we asked our respondents to rate their satisfaction with our magazine on a scale from 0-10 and it resulted in a final average score of 8.6. With our allotted margin of error and confidence level we can be 95% certain that if we surveyed all 1000 subscribers that our average score would be between 8.1-9.1.
