A confidence interval in statistics is a range of estimated values within a set parameter. It can be used to measure the certainty of an estimated population value (like the mean) from sample data.
CI is the confidence interval x̄ is the sample mean tα/2 is the critical value from the t-distribution based on the desired confidence level and the degrees of freedom (for example, tα/2 = 2.093 for a 95% confidence level and 24 degrees of freedom) ...
