The confidence interval is a range between a lower and upper bound. These bounds are equal to the sample mean minus the margin of error and the sample mean plus the margin of error, respectively. You can use ou

This simple confidence interval calculator uses a t statistic and two sample means (M1 and M2) to generate an interval estimate of the difference between two population means (μ1 and μ2).The formula for estimation is:μ1 - μ2 = (M1 - M2)± ts(M1 - M2)where:...
This Confidence Interval Calculator calculates the confidence interval for group of data, given we have the mean, standard deviation, and sample size for the data unit. The confidence interval allows us to quantify how confident we can feel a group of data is from its mean value. ...
