Question

independent practice
which of the following would be a good survey question?
what is your annual salary?
are you employed? if so, what is your annual salary?
what video games do you play?
do you play video games? if so, what is your annual salary?

Explanation:

A good survey question should be relevant and not ask for sensitive information (like salary) from those it doesn't apply to. The first question asks for salary regardless of employment status (sensitive if unemployed). The third question is too general about video - games. The fourth question wrongly links video - game playing to salary. The second question first checks employment (relevant) and then asks for salary (only from those employed, reducing sensitivity).

Answer:

Are you employed? If so, what is your annual salary?
