T Procedures

Statistical methods based on the t-distribution that are used to estimate population parameters and test hypotheses, especially when sample sizes are small.

Probability Calculations

The process of determining the likelihood of a given outcome, often expressed as a number between 0 and 1.

Normal Data

Data that follows a normal distribution, characterized by a bell-shaped curve where most observations cluster around a central peak and probabilities for values taper off equally in both directions.

Alternative Hypothesis

A statement that contradicts the null hypothesis and is tested for possible acceptance in hypothesis testing.
