I just uploaded the iClicker 2 data from last Wednesday's lecture. Here are some concepts to help you understand what you see in your grades page:

1. Each lecture is indicated by the capital letter "L" followed by a number. L5 indicates Wednesday's lecture, L6 would have been Friday's lecture, L7 will be Jan. 23's lecture, and so on.
2. The 20 points on your semester grade come the number of items you answer. See the syllabus for details.
3. The number of items you answer is tabulated in the "answered" row. E.g., the "L5 answered" row shows how many items you answered last Wednesday.
4. The number you actually get correct is tabulated in the row titled "correct". E.g., your "L5 correct" row states how many questions last Wednesday you actually got correct.

I am still figuring out the most graceful and efficient way to display all this data, but the data ARE in there.
