Definitions:

Confidence Interval

A range of values, derived from the sample data, that is likely to contain the value of an unknown population parameter with a specified level of confidence.

Mean

The central value of a dataset, calculated as the sum of all values divided by the total number of values.

Standard Error

Standard error measures the accuracy with which a sample represents a population, quantifying the variability of the sampling distribution of a statistic.

Confidence Interval

A variety of values taken from sample data, expected to encompass the value of a not yet known population attribute.
