RE: Test 1 results

Test 1 grades are in.

There was about a 3 point curve added to the data.

TEST1RAW is the raw number of items correct.

TEST1PCT is the percentage of items correct - take your number correct, divide by 40, and multiply the result by 100.

TEST1ADJ is your CURVED or ADJUSTED SCORE. It is what will be used in the final grades. Basically, it takes your standardized score, or z-score, and adds it to 80.

To insure that the different test versions were "fair" we compared the means of the four different versions. They were all quite close to one another and statistical tests showed the different versions were equivalent.

When I have to curve a test, I shoot for having about half be As and Bs, and about half be below that. The grade distribution, after adjustments, appears immediately below:

A RANGE	  14
B RANGE	  38
C RANGE	  34
D/F RANGE 13

Here are the descriptive statistics about the test

	         N	Minimum	Maximum	Mean	Std. Deviation
TEST1RAW	99	21	38	30.71	3.569
TEST1PCT	99	52.50	95.00	76.7677	8.92323
TEST1ADJ	99	55.50	98.00	79.7677	8.92323
Valid N (listwise)	99			

IF YOU HAVE QUESTIONS OR CONCERNS about your individual test, or individual items, please see Ms. Garcia or me during regular office hours, or, if those are inconvenient, make an appointment and we will chat.
