Cumulative & Relative Freq. (L1+L2 from TI-83)

Hopefully this can be solved quickly ( :) ), but I'm wondering how to
calculate functions on Excel (2007) in a similar manner as the TI-83 /84 does
in the L1 and L2 sections, under its "STAT-EDIT" function. I am able to
calculate the Mean, Median, and Standard Deviation accurately when only using
one row/column of information, but when I attempt to put two together, (like
the L1 and L2 section) it doesn't match.

If ANY of that makes sense, PLEASE let me know. :) Thank you all in
advance, and have a wonderful day!
