Suicide Bombing Lahore Pakistan
On 27 March 2016, Easter Sunday, at least 75 people were killed and over 340 injured in a suicide bombing that hit the main entrance of Gulshan-e-Iqbal Park, one of the largest parks in Lahore, Pakistan. The attack targeted Christians who were celebrating Easter. Of the 75 dead, 14 were identified as Christians and the rest (61) as Muslims. The majority of victims were women and children. Jamaat-ul-Ahrar, a group affiliated with the Pakistani Taliban, claimed responsibility for the attack. The attack led to worldwide condemnation and national mourning throughout Pakistan. Pakistan also launched a widespread counter-terrorism operation in South Punjab, arresting more than 200 people.
Specific Hypothesis and Results
The GCP event was set for 6 hours beginning at 08:30 local time. The result was Chisquare 21530.152 on 21600 df, for p = 0.631 and Z = -0.333.
The following graph is a visual display of the statistical result. It shows the second-by-second accumulation of small deviations of the data from what’s expected. Our prediction is that deviations will tend to be positive, and if this is so, the jagged line will tend to go upward. If the endpoint is positive, this is evidence for the general hypothesis and adds to the bottom line. If the endpoint is outside the smooth curve showing 0.05 probability, the deviation is nominally significant. If the trend of the cumulative deviation is downward, this is evidence against the hypothesis, and is subtracted from the bottom line. For more detail on how to interpret the results, see The Science and related pages, as well as the standard caveat below.
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.
