Hi everone!

Does anyone know the formula that Casio FX-9860 G (or newer models) use for finding the outliers? I am talking about the ones that you can show when drawing box plot in the STAT menu.

The default formula that I use in IB is that an outlier is x: Q3+1.5IQR < x < Q1-1.5IQR . But there are other defitions out there, such as everything that is more than 3 sigma away. However, no CASIO manual I have seen tells which one is used in the calculator.

Greatly appreciate your help!
