   Informally, in frequentist statistics, a confidence interval ( CI) is an interval which is expected to typically contain the parameter being estimated. More specifically, given a confidence level (95% and 99% are typical values), a CI is a random interval which contains the parameter being estimated % of the time.

   What is a 95% confidence level?

   • For example, if you construct a confidence interval with a 95% confidence level, you are confident that 95 out of 100 times the estimate will fall between the upper and lower values specified by the confidence interval. Your desired confidence level is usually one minus the alpha (α) value you used in your statistical test: Confidence level = 1 − a

   How are confidence intervals evaluated?

   • In other terms, the confidence intervals are evaluated using the given confidence level from an endless number of independent samples. So that the proportion of the range contains the true value of the parameter that will be equal to the confidence level. Mostly, the confidence level is selected before examining the data.
