Hi all,
I need to create a full random selection of 5% from a group (>1000000 elements).
The only criteria is, that all elements should have the same probability to be selected.
The selected 5% will be compared against the full base later on, but there are no predefined attributes/segments for that.
I want to know if it can be measured how perfect is the selection, because I need to make some test cases. Is there any usual value for what is acceptable as "full random"?
Thanks for your help!
