Stats Analysis 2

• Tricky: There were 4 questions in which 25% more students selected an “incorrect” alternative than selected the "correct” answer. This could be a result of student misunderstanding OR the official answer is incorrect.

• Note that Question #1 is typical. Most students answered correctly, but some made other choices and 1 left it blank (X).

• This test had 4 choices per question, but the "largest valid answer” was set to “E” when the test was added. Thus “E” values are empty.
