Definitions:

Confidence Intervals

A stretch of values, from sample data analysis, that is envisaged to hold the value of an undefined population characteristic.

Outliers

Observations in a data set that are significantly distant from the other observations, potentially indicating variability in measurement or experimental errors.

Confidence Intervals

A range of values, derived from sample statistics, that is believed to contain the true population parameter with a certain level of confidence.

Unknown Parameters

Quantities in a statistical model that are not known a priori but are estimated from data.
