# Help with weighted random sample in excel

I have a list of 14,561 people. We need to do a survey and we want to include about 5,000 random people total, but weighted based on the group they belong to (defined by L4 leader).
I calculated really quickly that if I include about 35% of people for each L4 I get to the 5,000ish I need. So if an L4 group has 1,000 people I include a random list of 350 people from that L4 group. If a group has 100 people I include 3 random people from that group.

How can I write some formula that lets me choose a certain number of random people from each L4 group?

I have a table with how many people each L4 has (L4 name frequency), and how many the 35% would be (desired size of each random sample). I have 50 L4s.

This does not need to be exactly perfect, but the sample really needs to be representative of the population of each group. Any ideas?

Test for Multiple Conditions in IF?
Use AND(test, test, test, test) or OR(test, test, test, ...) as the logical_test argument of IF.

BUMP- any ideas anyone?

Excel contains over 450 functions, with more added every year. That’s a huge number, so where should you start? Right here with this bundle.
