1. Name your topic: I am interested in ____________.
EX: (I am interested in substance abuse.)
2. Add a question: I am interested in _______________, because I want to find out (who, what, when, where, why, how).
EX: I am interested in substance abuse, because I want to find out why teens become addicted.
3. Add a reason: I am interested in _______________, because I want to find out (who, what, when, where, why, how), to understand (how, why or whether).
EX: I am interested in substance abuse because I want to find out why teens become addicted, and whether early childhood poverty plays a role.
Now turn it into a question:
Is there a correlation between early childhood poverty and substance abuse as a teen?
This is still a bit clunky, but notice this meets the AARF requirements. Also note, we don't ask "what is the correlation" because 1) that just asks you to list and 2) the question "what" implies there IS a correlation, so is somewhat biased.
Yes/No question are fine, as long as you realize the answer is always more complicated than yes/no. (If it isn't, it's not a good RQ!)
