Hi, I need to produce a cumulative frequency chart with the following data. I
am new to this concept on excel so any help will be grately appreciated. here
is the data:

Sentence Length Frequency Cumulative Frequency
1-10 9 9
11-20 12 21
21-30 15 44
31-40 8 49
41-50 1 50


Any help would be appreciated. I hope that i have made myself clear!
Thanks a lot,
Chris Grant
