Normally-distributed data forms a bell shape when plotted on a graph, with the sample mean in the middle and the rest of the data distributed fairly evenly on either side of the mean. The confidence interval for data which follows a standard normal distribution is: Where: 1. CI = the confidence interval 2. X̄ = the … See more A confidence interval is the meanof your estimate plus and minus the variation in that estimate.

Confidence Intervals: Interpreting, Finding & Formulas
WebJan 21, 2024 · Confidence interval (CI) of the true value of a parameter is estimated using a sample. The interpretation of that CI is that many (say 100) such samples are taken, about 95% of the time the confidence interval formed from those samples would contain the true parameter value. A variation of this definition can be seen. This link has some answers. WebApr 6, 2024 · Nonparametric confidence distributions estimate statistical functionals by a distribution function on the parameter space, instead of the classical point or interval estimators. The concept bears analogy to the Bayesian posterior, but is nevertheless a completely frequentist concept.
