Calculating confidence intervals in R is a handy trick to have in your toolbox of statistical operations. A confidence interval essentially allows you to estimate about where a true probability is based on sample probabilities at a given confidence level compared to your null hypothesis. The confide...
How to Compute a Confidence Interval in 5 Easy StepsJeff Sauro
What is a confidence interval? A confidence interval is a range of estimates in a sample distribution where a true population value lies, with a certain level of confidence or probability. Confidence intervals are often used to determine the certainty of a true estimated value (such as a mean...

A confidence interval is a mathematical concept that expresses how likely a range will contain the mean of a data set.
The confidence interval of the mean is a statistical term used to describe the range of values in which the true mean is expected to fall, based on your data and confidence level. The most commonly used confidence level is 95 percent, meaning that there
