confidence interval

[sujeto]

A type of interval estimate commonly used by scientist to report a plausible range of values for a population parameter based on a subsample dataset. The confidence interval is named after the fact that its construction relies on choosing a confidence level that reflects the degree of uncertainty associated with the estimation. The confidence level represents the percentage of confidence intervals that can be expected to include the true population parameter if all possible confidence intervals were calculated from all possible subsamples.
