Assuming you know how to create a histogram (Data Analysis Add-in)

-Create histogram;
-Add up the number of pieces of data (frequency)
- Divide each population by the total number of pieces of data,
-Add this value to the preceding value
-Total should add up to 1.0 (100%)
Graph the total as y axis and the bin as the X-axis- and there's your
cumulative frequency graph
