Is it free to embed a Stat-Tools calculator?

Yes. Every calculator can be embedded for free on any website, blog, or learning platform. There is no sign-up, no API key, and no limit. We only ask that you keep the small attribution link shown beneath the calculator.

How do I embed a calculator?

Open any calculator, click the Embed button to reveal a ready-made iframe snippet, and paste it into your page's HTML. Or build the snippet yourself by adding ?embed=1 to the tool's URL and placing it in an iframe.

Will the embedded calculator work on mobile?

Yes. Embedded calculators are responsive and resize to fit their container, so they work on phones, tablets, and desktops.

Embed Free Statistics Calculators on Your Site

Every calculator on Stat-Tools is embeddable for free. Teachers, bloggers, and course authors can place an interactive t-test, confidence interval, or distribution tool directly on their own page — students never have to leave your site. There is no API key, no account, and no usage limit.

Quick start: copy and paste

Here is a ready-to-use embed for the T-Test Calculator. Paste this into your page's HTML wherever you want the tool to appear:

<iframe src="https://dackohn.com/stats/tools/t-test.html?embed=1" width="100%" height="640" style="border:1px solid #e5e7eb;border-radius:12px;" title="T-Test Calculator — Stat-Tools" loading="lazy"></iframe>
<p style="font-size:13px">Powered by <a href="https://dackohn.com/stats/tools/t-test.html">T-Test Calculator</a> from <a href="https://dackohn.com/stats/">Stat-Tools</a></p>

Embed any calculator

You do not need this page to embed a tool. Two ways:

Use the Embed button. Open any calculator and click the 🔗 Embed button near the results. It reveals a copyable iframe snippet tailored to that tool.
Build it yourself. Take any tool URL, add ?embed=1, and put it in an <iframe>. The ?embed=1 flag strips the site header, footer, and ads so only the calculator shows.

Styling and sizing

The iframe is fully responsive — set width="100%" and it fills its container on any device. Adjust height to suit the tool (most fit comfortably in 600–720 px). You can wrap it in your own container, add a border-radius, or set a max-width; the calculator inside adapts.

Attribution & licence

Embedding is free for any use, including commercial sites. The one condition is simple: keep the “Powered by Stat-Tools” attribution link shown beneath the calculator. It helps others find the tools and keeps them free. The embedded calculator also shows a compact attribution inside the frame.

Frequently asked questions
