WORK PROBLEM

[Guest]

Hello,



I'm currently new here and i am racking my brains out with a problem my client has given me.

I don't know if this belongs here tho.


So, i work an advertising firm and had a project to collect and register mobile numbers to our app. It works as a data gathering app of of some sorts and will be used for the dissemination of their advertising materials. Anyhow we had a big blunder as according to them, we had gathered almost 200,000 entries but have 127,730 duplicates. Of the 127,730 duplicates, 23,232 unique mobile numbers were used.



What i want to know is how do i get to know the the actual or approximate number of mobile numbers used for each of the first column figures. (i.e out of 23,232 mobile numbers how many was used 2 to 10 times, 10 to 20 times and so on)

I can't provide other data as client is furious at us. Thank you for your help.
