I have excel data as shown below. I want to have a range of sf like 0-0.05,0.05-0.1, 0.1-0.15,0.15-0.2....and so on. Now, 2nd column of data represents number that have corresponding sf. I want to count the number and do cumulative that falls within the range of sf(as above) like 0 to 0.05, 0.05-0.1,...and so on and would like to put in array. Finally, I want to plot sf(0,0.05,0.1,0.15...) vs num(cumulative sum). Let me know your suggestion. I used count function but giving me error. Thank you.
