## Determining Sample Size: Find the # of response you need | Qualtrics

Lower margin of error requires a larger sample size. What confidence level do you need? Higher confidence level requires a larger sample size. What is the population size?

### Solved Example Problems with Steps

If you don't know, use What is the response distribution? This is the minimum recommended size of your survey. If you create a sample of this many people and get responses from everyone, you're more likely to get a correct answer than you would from a large sample where only a small percentage of the sample responds to your survey.
