School Shooting, Winnenden, Germany
Hans Wendt alerted me to yet another school shooting, this one in Winnenden, Germany.
From Yahoo! News: A 17-year-old wielding a Beretta 9 mm pistol burst into classrooms at his former high school Wednesday and gunned down students -- some of whom died with their pencils still in hand -- in a rampage that ended with 15 dead before he took his own life, authorities said.
Police said the suspect was a German teen who was a below-average student at the school of about 1,000 pupils, but managed to graduate last year.
Police received an emergency call from the school at 9:33 a.m. They stormed the school, but the gunman fled, killing two more teachers, then two men at a car dealership, before killing himself.
The GCP event was set for an hour before to 4 hours after the shootings began, 07:30 to 12:30 GMT. The result is Chisquare 17926.985 on 18000 df, for p = 0.649 and Z = -0.382.
It is important to keep in mind that we have only a tiny statistical effect, so that it is always hard to distinguish signal from noise. This means that every "success" might be largely driven by chance, and every "null" might include a real signal overwhelmed by noise. In the long run, a real effect can be identified only by patiently accumulating replications of similar analyses.
