About Knocise

Make the abstract
feel tangible.

Knocise is a small collection of interactive explanations for people who want to understand the idea behind the formula.

Learning through a small experiment

A calculator can give you a number. An experiment can help you see why that number makes sense. We pair editable inputs and visual results with a plain-language explanation, a worked example, and the assumptions that make the model valid.

What you can expect

The first collection focuses on introductory probability and statistics. Calculators use the formulas shown on each page. Simulations draw finite random samples, so their results vary. We distinguish simulated observations from theoretical probabilities.

Every topic links to further reading. Knocise’s explanations and interactive code are prepared with AI assistance, and the calculations are checked against known mathematical results. They are educational resources, not a substitute for a course or an expert’s assessment of a real-world decision.

Your inputs stay here

Our experiment code runs in your browser and does not upload your inputs or require an account. We do not add advertising trackers or marketing cookies. The hosting service may process routine request information, such as IP addresses, to deliver and protect the site.

A collection that can grow

New experiments will follow the same approach: something you can try, a result you can inspect, and an idea you can take away.
