Definitions:

Normal Distribution

A symmetric probability distribution centered around the mean, indicating that occurrences close to the mean are more common than those far away from it.

Confidence Interval

A spectrum of values calculated from statistcal samples which is expected to cover the value of a not yet known population trait.

Non-Normal Population

A population that does not follow a normal distribution, characterized by skewness, kurtosis, or other non-normal traits.

Bootstrap Procedure

A resampling method used to estimate the distribution of a statistic by repeatedly sampling with replacement from the data set.
