Analysis of school shootings by day of the week

I got data from CNN on school shootings from here

https://www.cnn.com/interactive/2019/07/us/ten-years-of-school-shootings-trnd/

and of the 199 shootings I was curious if one day of the week was more dangerous than others...

Given the amount of data, I believe this is statistically meaningful...

So I wrote some software to count shootings by weekdays... and this is what I got:

Sunday - 4
Monday - 23
Tuesday - 38
Wednesday - 31
Thursday - 36
Friday - 61
Saturday - 6

Friday stands out as the most dangerous day at a school. One might think that this could be related to after school activities on Friday nights... but the charts that CNN include do not show that.

Saturday and Sunday are obvious... The other days seem to center around 30 shootings or so for the weekday. Friday is the one that really is statistically different.

The sad thing is that we have this data at all.

The song "I don't like Mondays" maybe should be changed a bit although that was the reason given by a school shooter for a shooting on 29 January 1979.
