Confidence Interval Calculator

 A confidence interval is a kind of band or range that's calculated from sample data. It tells you how much variation to expect when different samples are taken until the true value has been found. As an example, let's say 9 out of 10 people voted for you in a survey and it has been conducted with a 95% confidence level, this means that if we were to repeat the survey over and over again, no more than 5 times may the number change before repolling yields only 90% results.
