Statistical testing is a structured method to evaluate hypotheses using sample data and quantify uncertainty in conclusions. It covers selection of test statistics, significance levels, and error types. Used in analytics, quality assurance and A/B testing for data-driven decisions. Requires clear hypotheses, adequate sample sizes, and assumption checks.
Use this profile to understand the building block briefly, place it in the model, and switch to the 360° assessment when needed.
Executable approach: can be applied and produces an outcome.
What organizes, connects, or makes decisions possible.
Statistical testing uses sample data to assess whether an observed deviation is compatible with a stated assumption.
The approach grew from probability and sampling theory as science and quality work needed formal decisions under uncertainty. References such as the NIST handbook organize the test steps commonly used today.
State null and alternative hypotheses, choose a test and significance level, calculate the test statistic, and interpret the result in its data context.
The starting assumption that data may support or challenge.
A threshold set in advance for rejecting the null hypothesis.
A measure of how unusual the data would be under the null hypothesis.
The approach separates random variation from meaningful evidence and makes uncertainty visible in experiments and quality decisions.
