RE: Results of Test 2
Results sorted by your 4 digit ID number. Test2Raw is your "raw" number of items correct out of 50. To get your "raw" percentage just multiply that number by 2.
There is a curve. It appears in the column TEST2ADJ. It curves up. It is this percentage that I will be using in final grades. If it is 90 or above you are in the A- to A range. If it is in the 80s you are in the B- to B+ range. And so on.
We checked; there were no significant differences between mean scores across the 3 different versions. Test statistics appear below
