QCalc is a random statistics calculator that I wrote. It's in QML with a C++ backend for the heavy lifting. It's been tested and verified to work on Linux and Android (although it's using Qt, so it should work anywhere). And who knows, it may suddenly acquire other features as well...
Type in a comma-separated list of numbers (e.g. "1, 2, 2, 5, 8") (spacing does not matter) and press Enter or click "Use this data set".
