📌

I built this Standard Deviation Calculator to make statistics easier to calculate, understand and verify. It supports both population and sample calculations along with advanced statistics such as quartiles, percentiles, Z-scores, outlier detection, confidence intervals, grouped data and visual charts. The goal was to create a practical browser-based statistics tool that students, researchers, analysts and anyone working with datasets can use without installing software. I’d love to hear which statistics feature you find most useful and what you would like to see added next.
