Disclaimer

General information only

The content on this website, including articles, guides and the free calculators and text tools, is provided for general information and educational purposes. It is not legal, medical, financial or other professional advice, and it does not replace the judgement of a qualified statistician, researcher or advisor who knows your situation.

Accuracy of tools and results

The free tools use widely accepted formulas and approximations. For example, the power-based sample size results use a standard approximation to the noncentral F distribution and can differ slightly from dedicated software, and the sentiment checker is a simple word-list method for English text that cannot understand sarcasm or context. Results may contain errors or may not suit your data or study design.

Before using a result in a thesis, publication, policy decision, grant proposal or business decision, please verify it with specialist software or a qualified analyst, and check that your data meet the assumptions of the method.

No guarantee of outcomes

We make no promise that using our tools or advice will produce a particular research, academic, business or financial outcome. Statistical significance, reliability scores and sample size targets depend on your data, design and context.

External links and advertising

Examples and sample data

Sample data, examples and illustrations on tool pages are made up to show how a tool works. They do not describe real studies or people.
