Key Concepts

Type II Error

A Type II error occurs when the null hypothesis is not rejected even though the alternative hypothesis is true. This error represents a false negative outcome, meaning the test fails to detect a real effect or difference that actually exists.

Type I Error

A Type I error occurs when the null hypothesis is incorrectly rejected even though it is actually true. This error represents a false positive finding, meaning the test indicates a significant effect or difference when none actually exists.

Null and Alternative Hypotheses

The null hypothesis represents a baseline assumption or status quo that there is no effect or difference, while the alternative hypothesis represents the statement or effect that the test is trying to provide evidence for. These hypotheses form the foundation of the hypothesis testing process.

Hypothesis Testing

Hypothesis testing is a statistical method used to make inferences or decisions about a population parameter based on sample data. It involves establishing two competing hypotheses – the null hypothesis and the alternative hypothesis – and using evidence from the data to decide which hypothesis is more likely to be true.
