This is a graph showing no correlation between a concocted metric & training hours data. Makes no sense to post- not beautiful data.

This is the right response. The y-axis data doesn’t make any sense. You may as well throw auto fatalities in there, since we’re just combining random-ass data. Training police more will probably have the same amount of impact on auto fatalities as it will violent crime.

Thank you. Incredibly misleading analysis normalizing by violent crimes. Many untrained people won’t notice this either, making this actually feel manipulative

  1. That there is no correlation is exactly my point in reply to the original post to which this is a reply - https://www.reddit.com/r/dataisbeautiful/comments/ywowl8/us_states_police_training_v_shootingsviolent/
  2. What you're calling a 'concocted' metric is actually a derived metric and is perfectly valid.

Still a correlation. Weaker looking one, but it’s there. Strike out the three obvious outliers and concentrate on the central data points.

Doesn't look like a clear one to me. What would you say the correlation is exactly?

It’s not a great correlation but it’s there. Strike out the big outliers, (VT, CT, and HI). You’re left with a range around 400-1000 of training. If you look at the derived metric of shootings/ crime there’s a definite weight towards more shootings at the lower end of the training scale compared to the top.

Granted, the bulk of the dataset shows that by that metric the majority of states have relatively low numbers, but those that are elevated are all on the lower end of the 400-1000 scale and the magnitude of the elevation is weighted towards the lower end.

This is a kernel density plot with the 'outliers' CT, HI, MN, ND, VT removed to clarify that central section.

Agreed, there does seem to be a bulge in the centre - around 650 hours, but still doesn't fully support the assertion that more training = less fatal shootings
