I'm trying to find skewness for this distribution. I know how the
skewness function works but I'm not sure how to deal with this dataset
I have.

Bin..........Freq
0-10........78
10-20......2589
20-30......922
30-40......11


So, all I know is how many values are in each bin (not what the values
are themselves). Does that mean I have to type in an arbitrary value
of the 2nd bin 2589 times in order for Excel to understand what I'm
looking for? Anyone know of a shorter way? Thanks.
