Whenever you see this kind of aggregation you can be certain that you there will lies, damned lies and statistics. Let me guess - if the authors did by 5 groups the results they got were not saying something they liked. Or at least they should have put any kind of proof that the rate of ticketing for all of those aggregated groups were quite similar.
- dragonwriter 2y ago> Let me guess - if the authors did by 5 groups the results they got were not saying something they liked. The main reason likely is that US race (treating Hispanic ethnicity as a race trumping nominal racial categories, so the other categories all are implicitly prefixed by “non-Hispanic”) is something like (in 5 categories): 59% White, 19% Hispanic, 13% Black, 6% Asian, 3% Other/Mixed. Or, in two categories: 59% White alone, 41% Other The two-group breakout takes far less data to get equal statistical utility for its smallest group when compared to the 5 group breakout (that's true even if you don't really care about the Other/Mixed catch-all group in the 5-group breakdown, but only the other four.)
