Creating a Confidence Interval for the Difference of Two
Confidence Interval. In statistics, a confidence interval is an estimated range of likely values for a population parameter, for example 40 ± 2 or 40 ± 5%.

Confidence Intervals for Two Samples
confidence interval calculator 2 samples
The difference between the sample means is a point estimate of the difference between the population means, but it can be useful to assess how reliable this estimate is using a confidence interval. A confidence interval provides you with a set of limits in which you expect the difference between the population means to lie. The p-value and the confidence interval are related and have a
