I must say that the low rate of correct answers surprises me. I intended this question to be a relatively easy first question in a series (hence the "1" in the title). I have already submitted the second one, and I won't change that - but I'll have to rethink the difficulty level of the remaining planned questions (that I did not submit yet).
The number of ways of answering correctly: 1
The number of ways of answering incorrectly: many
The is no "partially correct" option. I might have complained about mixing 4 different ideas (and their negation) into the multiple-choice answer, but I thought "Grow up, these are professionals we're talking about"
So I'm sharing this thought to possibly explain why results are skewed to 9% correct.
I think there's also a psychological impact of 8 checkboxes - the answer seems simple enough, but then there's the second-guessing. After that first moment of hesitation, we're much less likely to check all (and only) the right boxes.
Anyway, I admit I was guessing at the answers - but I think this is a great example of an edge case of SQL ServerCentral Question of the Day. Maybe if more questions were written this way we'd be more accustomed to it?
