Definitions:

Value Of T

A calculated statistic used in t-tests that measures the size of the difference relative to the variation in the sample data, commonly used to test hypotheses about means.

Confidence Estimate

An interval estimate calculated to indicate the reliability of an estimated range in which a population parameter lies.

Observations

Data points or values that have been collected or measured in a study or experiment.

Value Of T

The value of t, often found in t-tests, quantifies the difference between an observed sample mean and its hypothesized population mean value, measured in terms of standard errors.
