The number of observations or replicates included in a statistical sample, crucial for the validity and accuracy of an experiment.

Degrees of Freedom

The number of independent values or quantities that can vary in the analysis without violating any constraints.

Confidence Interval

A collection of values, resulting from statistical sampling, that is expected to house the value of a non-identified population parameter.

Degrees of Freedom

This parameter represents the number of values in a statistical calculation that are free to vary, crucial for determining the outcome of various statistical tests.
