Definitions:

Bootstrap Standard Error

A measure of the variability or dispersion of a statistic's sampling distribution, estimated using the bootstrap resampling method.

Critical Value

A threshold value in hypothesis testing that defines the boundary of the rejection region; values beyond this indicate statistical significance.

Confidence Interval

A spectrum of numerical values, derived from the analysis of a sample, likely to enclose the value of an elusive population parameter.

Trimmed Mean

A trimmed mean is calculated by removing a certain percentage of the largest and smallest values from a data set, then computing the mean of the remaining data.
