Notes for class -- Air Power during the Persian Gulf War

Here are the notes for today's class on the article by Daryl Press.

Midterm II -- Summary Statistics

The results are in for the second exam, and here are some brief summary statistics:

Total Number of Exams: 43
Mean score: 81.30
Modes: 84 (3 exams) 93 (3 exams) 99 (3 exams)
Range: 100 to 39 (the full description is below)

CURVE: These statistics include a 15 point curve that I added because of a miscalculation on the test sheet.

NOTE(!!!): I again regressed the effect of attendance on overall grade for the exam. After controlling for several other factors, missing one class decreased a test score by almost 4 points, on average. Thus, if a student misses four classes, then student is likely to score an 84, holding everything else constant. Attendance matters. The 15 students (almost one-third of the class) who scored an A- or above on the exam only missed a total of 8 classes total among them!

Here is the distribution of grades:

"Clash of Civilization" notes

Here are the lecture notes for this segment of the class. Note: Students who have difficulty with some of the terms may wish to consult my previous post on political analysis, which is here.

Polarity Notes

Here is the first set of lecture notes on polarity. And here is the second set of notes.

Deterrence Notes

Here is the first set of notes on deterrence. Note that the outline follows the Long Peace article by Gaddis (also available on this blog). The second set of notes is here and is only loosely supported by the readings.
