by Zach Bobbitt April 20, 2020. A confidence interval for a difference between means is a range of values that is likely to contain the true difference between two population means with a certain level of confidence. The formula to calculate the confidence interval is: Confidence interval = ( x1 - x2) +/- t*√ ( (s p2 /n 1) + (s p2 /n 2 ))
