7/n Statistically, the choice to use the crude number of daily suicides is very strange. Suicides don't happen every day in this dataset (there are too few), and crude numbers are usually not very useful without a denominator

19/n Ultimately, the numbers just aren't there to take home much meaning from this in my opinion. Overall, there have been no changes in suicide rates by race in Maryland in the first half of 2020 - the figures show that quite clearly

23/n There may be a statistical test that shows significance of a sort here, but conceptually I don't think there is much meaning to be garnered from numbers like this
