You know, I was prepared to post a rough list of all of the wrong statistical interpretations that you have posted in literally every thread I remember you posting a stat, but I don't even have to. This is the perfect example. I assume you're posting this in reference to that study having less than 10 sample cases for what you interpreted as a black-on-white epidemic. That's not what your quoted text means. "Series incidents "means a crime or a group of crimes involving the same victims and perpetrators. So, if a guy beats his girlfriend several times, it is capped at ten within the statistics.
In the VERY NEXT SECTION of the page you linked to there is this:
So, yeah, you don't understand facts. At all. And this is a habit for you. EVery single time I have looked into any stats you posted, they were either complete bullshit it interpreted wildly inaccurately.
They explain why they use a sample of ten. It corrects any statistical imbalances that can skew the data. It's right there.
This is from a PDF you can download from the same site.
Given the findings from this research, BJS will enumerate
series victimizations using the victim’s estimates of the
number of times the victimizations occurred over the past 6
months, capping the number of victimizations within each
series at a maximum of 10. This strategy for counting series
victimizations balances the desire to estimate national rates
and account for the experiences of persons with repeated
victimizations while noting that some estimation errors exist
in the number of times these victimizations occurred.
