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.

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. Execution happens locally in your browser — no data leaves your machine.
