Hello:

I have a large data set in excel and I would like to know the quickest (and easiest) way to get a random sample of the data.

The data has several different usernames in a column called "Assigned to" and I need to get 10 random records from each user.  

Thank you in advance.

Sort by usernames. Use the =RANDBETWEEN() function to generate a random number 10 times and pick those rows as your sample.

Ok that sounds good.  Question for you:  How do I get the bottom and top numbers for each user?

I created a counter for each record within that users "group" of records.  But how do I get the MIN and MAX of that counter?

Thank you for you help

Once you sort your data, then MIN number will be the row where that user's data starts and the MAX number will be where that user's data stops.

Yes and the MIN will always be 1 because that's where I start my counter.  But is there a formula or function I can use to determine the MAX?

The MIN should not always be 1 if it is a sorted list. You can use =COUNTIF() funtion to find how many rows there are for each username, then the MAX will be equal to the MIN + COUNTIF(username)
