Confidence Interval Calculator Online

The Confidence Interval Calculator online tool can be used to calculate the confidence interval for a population mean. A confidence interval is a range of values that is likely to include the true value of a population parameter. The confidence interval calculator helps you find the range of values that is likely to include the true value of a population parameter by entering information about the sample and the level of confidence you want to use.

A confidence interval is a way to estimate how likely it is that a population parameter falls within a certain range. The confidence interval calculator helps you to figure out that range. You just need to enter some information about how many people are in the group you're studying (the sample), what the average score is for that group (the mean), and how much variation there is in scores within that group (the standard deviation).
