ttest()

Statistics

ttest() is a MATLAB®-compatible statistics function for one-sample t-test. tests whether the mean of x differs significantly from mu (default 0). returns { t, p, df, ci } with t-statistic, two-tailed p-value, degrees of freedom, and 95% confidence interval. Run it online in your browser with SimLab — free, no install, no license required.

Frequently Asked Questions about ttest()

Is the ttest() function free to use in SimLab?

The browser workspace requires no MATLAB® license or installation. Connected features require network access and may have account, tier, availability, or usage limits. You can open ttest() and 510+ other MATLAB®-compatible function references at simulations4all.com/simlab.

Do I need to install MATLAB to use ttest()?

No. SimLab’s core parser, workspace state, and most functions run locally in your browser. The ttest() function requires no MATLAB® license or desktop software download.

What does ttest() do?

One-sample t-test. Tests whether the mean of x differs significantly from mu (default 0). Returns { t, p, df, ci } with t-statistic, two-tailed p-value, degrees of freedom, and 95% confidence interval. It is a MATLAB®-compatible statistics function available in SimLab with the same calling syntax as MATLAB® — typically: ttest(x).

Can I run ttest() in my browser?

Yes. Open SimLab at simulations4all.com/simlab, write or paste code that calls ttest(), and run it. This function’s calculation runs locally in the browser. SimLab session analytics, sharing, feedback, and eligible acceleration have separate network boundaries.
