    Using a calculator, like the FX-991EX classwiz

    How do you do it? is it possible?

    Seems to be a trick to it that i am not aware of and no one speaks about it in videos and so on...

    The 991EX Classwiz doesn't do interpolation.
    For grouped data you can estimate the mean using the midpoint and frequency in a table, but you can't find the median or quartiles for continuous grouped data.
