PS: At Circonus we have built technology that is explicitly addressing many of the statistical pitfalls that are explained in the post.
If you are looking for a monitoring vendor, who deeply cares about getting the the statistics right (especially around aggregating and analysing latency data), have a look at https://circonus.com / https://lps.circonus.com/statistics-for-engineers/ and/or reach out to me.

Thanks for this! Any chance you'll be running this class in a way I can attend any time in the near future in London? (I could be convinced to fly somewhere else in Europe for a couple days though)

Most certainly yes. I am planning on proposing it again for next years conference season. In particular SRECon EMEA 2020 in Amsterdam comes to mind.
PM me your email, and I'll put you on the mailing list.
This article is quite dated. I ran the Statistics for Engineers class at various conferences over the years, and updated the material. I literally just did a session at SRECon EMEA today [1]!
The course material is here: https://github.com/HeinrichHartmann/Statistics-for-Engineers...
Todays version includes new material about:
- How averaging percentiles breaks down
- How sub-sampling affects percentile calculations
- Comparison of "mergeable aggregation methods" like HDR Histograms, t-digest, etc.
If you liked the article, make sure to check out the github course material. It's much broader and more up-to-date.
