I do exactly the same thing and find that very few students, indeed take
advantage of this. They really do think they know the answer, or they don't
know enough to rationalize a challenge.

This procedure might be confusing to the students. The chance points
are the same for all students and operate like adding a constant to
everyone's test score. It's the student's position on the frequency
distribution that counts--at least, if you grade on a curve.

In grading some recent three-choice multiple choice quizzes, I noticed
that a couple of students got fives and one got a four which got me to
thinking that, over the course of five quizzes, students are actually

A student has conducted 2 memory experiments and she would like to
compare performance across the two (at least roughly).The problem
is that 1 of them was a 2-alternative forced choice test and the

If each of the group scores were converted to z-scores, wouldn't the z-score
mean for each group (by definition) be equal to zero? So you would end-up
comparing two zero scores (with a standard deviation of 1.00 for each group).
