Two years ago I also developed Excel files with random guess scores for various question types. Not in relation to multiple attempts, but also when applied in summative exams to calculate the relative P-value of questions (P'=P-randomguessscore) and, using those, the lowest score for which a student receives a score of 1 (in the Netherlands we use a 10 point grading scale) representing the random guess score for the test as a whole. Helen's report at least is written by a statistics expert (I worked with trial and error) and I love it. I would like to share my excel in this post or with Helen and write some more about this. Maybe I will put something up in my own blog. Kind regards, Silvester Dear Sally,

This post of yours has been on my list to respond to for quite some time now.

Two years ago I also developed Excel files with random guess scores for various question types. Not in relation to multiple attempts, but also when applied in summative exams to calculate the relative P-value of questions (P’=P-randomguessscore) and, using those, the lowest score for which a student receives a score of 1 (in the Netherlands we use a 10 point grading scale) representing the random guess score for the test as a whole.

Helen’s report at least is written by a statistics expert (I worked with trial and error) and I love it.

I would like to share my excel in this post or with Helen and write some more about this. Maybe I will put something up in my own blog.

Kind regards,
