If your population is smaller and known, just use the sample size calculator. What does that look like in practice? Here’s a worked example, assuming you chose a 95% confidence level, .5 standard deviation, and a margin of error (confidence interval) of +/- 5%. ((1.96)2 x .5(.5...

5% margin of error Population of 10,000 Using our spreadsheet, you can see that you should survey at least 370 people. And Survicate is currently working on a sample size calculator, so stay tuned! Once you have your sample size, you have to account for your response rate. You can expe...
Specify the level of accuracy you want from your research. The sample size directly determines the margin of error or the width of the confidence interval, two statistical measurements that can be used to judge how accurately your research tracks to the larger population. ...
In statistics, a confidence interval is also known as a margin of error. Given a defined sample size, or the number of test results that were produced from identical repetitions, a confidence interval will report a particular range within which a certain percentage of certainty in the results ...
