I'm just starting stats and we're working on just gathering population samples right now, and I'm a little confused on how to get a stratified sample.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

A club has 30 students and 10 faculty. (my book lists out the names of the students and the faculty so I can assign them numbers) The club can send four students and two faculty members to a convention. It decides to choose those who will go by random selection. Use Table B beginning at line 123 to choose a stratified random sample of four students and two faculty.

(Table B is a random number table at the back of my book- I know how to use that)

2. Relevant equations

N/A

3. The attempt at a solution

I've gotten the hang of using the random number table to pick a simple random sample; however, I don't understand how to do so for a stratified sample. Typically I would assign the group members numbers (in this case 00 to 29 or 01 to 30 for a group of 30), and then pick out the two digit numbers that fit in the desired sample from the random number table. When I have two groups though, and I need a certain number from each group, I don't know what the correct way of doing it is. Do I simply combine the student and faculty groups and number them 01 through 40 and keep picking until I get 4 students and 2 faculty, or is there a more correct way??

Thanks!
