Random Sample with multiple data points
I have a list of people with a large number of lines per person. I need to
randomly select two lines for each person. The report is preformatted and downloaded daily. The names are listed in column C. How can I do this? |

Random Sample with multiple data points
Say we have 20 "Mike" lines, then 10 "James" lines, then 50 "Sally" lines, etc.
It does not matter if the lines are grouped together or not. In an un-used column (say column Z), enter: =RAND() and copy down First the table by column Z. This will randomize the records. Then sort the table by column C. This will group the names together, but in a random order. All the "Mike"s will be grouped, but the order of the "Mike"s shuffled. Then just take the first two "Mike"s, the first two "James"s, etc. -- Gary''s Student - gsnu200847 "Jeremy" wrote: I have a list of people with a large number of lines per person.
