Since I'm still quite new to the site, I just wanted to poll what the general consensus is on voting down questions from people with very low rep:
As an example, I don't think the OP from this question really understands the difference between a categorical and a continuous variable. I saw that some had voted the question up, but I personally wanted to vote it down (and did) because I feel the OP didn't understand what he or she was asking.
Do you think this discourages new posters if they have their questions voted down? (Even if perhaps they received answers that are voted up?)
If you answered yes to question 1, is there some approximate metric, duration of account in days, or minimum rep before you believe a question should be voted down?
My motivation is that I really want to encourage my students to ask questions here, but I don't want to raise the noise level with questions that aren't well thought out. If we vote by consensus, I'd be happy to accept an answer -- but mods feel free to make this cw.
