I’m not the PP but wanted to answer to the newbie’s question “ Why the ranking is changed between teams on regional scale versus national scale?”. First of all, sometimes the regional ranking matches national ranking for those teams in questions. Other time, they do not match. Secondly, why the difference when they do not match? For example: 12”s : regional ranking : Metro 12 Travel (1) Metro 12 North (12) Metro Central (28) Metro East (29). National ranking: Metro 12 Travel (96) Metro 12 North (1179) Metro 12 East (2138) Metro Central (2252) So on the National Ranking scale Metro Central is last. 13’s : regional ranking : Metro 13 Travel (1) Metro 13 North (13) Metro 13 East (14) Metro 13 Central (28) Metro South PW (69) National ranking: Metro 13 Travel (67) Metro 13 East (556) Metro 13 North (1138) Metro 13 Central (1818) Metro South PW (3466) Notice the swapped ranking between 13 East and 13 North on the National ranking. Regional ranking is so far off between ranking of 13 East (556) and 13 North (1138) Club and Coaches often boast about their regional ranking (easy to show) to compete with other clubs in the same area, but the true performance is always showed in National ranking. Of course, there are exceptions as some very good local teams who do not want to travel far to compete but this is very rare. |
Sure, happy to. I'll send them as different posts because there is a lot of data. This data pull is directly from AES using national ranks for the last 4 years (Central did run teams in 2021 and South was still one region instead of 2). I used AI to format for easy text reading, so if any data is wrong its because of the AI transcription errors that sometimes occur. 2025 Metro results National Ranks, Ordinal = absolute ranking vs. Metro teams. I also ran the regional ranking data same way and ran a t-test for the regression (testing how predictive the regional rank was vs the national rank in overall win %, total wins, etc). The p-value was high indicating that regional ranks did little to predict the overall performance of the team. It appears that the regional data set suffers from data insufficiency issues discussed by multiple PP above. For example, in 2025 U15 only Metro South teams played more than half their matches against regional opponents. The other Metro teams played fewer than half of their matches in region, with Metro North plays just 16 matches against regional opponents compared to 48 total matches for the season in the national ranks. The disparity in games played means that teams with lots of regional matches ranked artificially higher than those with comparably fewer regional matches played. In other words the teams that played mostly local schedules appear stronger in the regional rankings even though the national data shows they are well below the performance of those teams that played more out of region matches. |
I'm Newbie, thanks for this very specific example. I now see that this happens, but I still don't understand WHY? What is different about what the criteria are for regional vs. national rankings that make Metro 13 East #556 and Metro 13 North #1138 in national rankings (so East better than North), but on regional North is 13 and East 14, so North better than East)? It seems like the order should still stay the same, so what is considered or weighted differently that changes the order? Totally appreciate you taking the time to post and explain all of this! |
Aaaahhh ok, NOW I get it, thank you! Sorry, didn't see this part when wrote previous message. Thanks! |

Happy to help. As they say "Lies, D**n lies and statistics". In this case the claim that started all this was based on the national ranks and the generally understood fact that national ranks are much more accurate than regional ranks, at least in CHRVA. The rebuttal to that used the regional ranks to try to prove their point, but as we've covered extensively now that rebuttal fell into the "statistics" bucket of the statement above. Often on DCUM there is an assumption that there are ulterior motives for posts and for some posters there definitely is. Some parents can get very wrapped up in their club and will defend it vigorously, others will have a bad experience or feel slighted when their DD doesn't make a team and trash a club constantly. Add in the anonymous club staff posts and you get a wide range of opinion that can be heavily biased. Without understanding the bias we sometimes take information shared at face value when we should be skeptical of it. Generally when you see over the top responses to statements of fact it's because that bias exists and they are trying to prove someone wrong in defense of their club. A big hint is all caps responses and attacking the post as completely invalid, FYI. But there's a small group of posters that generally have a "let the data tell us" approach. Those posters tend to have a sound understanding of the way rankings work, the relative performance of the teams and a good grasp of the strength of schedule impacts on rankings. They also know a lot of the players and some have been around the game for a long time, and their posts reflect that. They are biased some too, but they generally change their minds when presented with data (See the discussion re: recruiting for example). If you read through the threads you'll see these posters sharing data in a variety of threads like the metro vs. paramount debates, helping new families understand the difference between a 1 team at Club A and a 2s team at Club B, etc. I'm not sure how many of them responded in this thread, but it feels like at least 3 and they all said versions of the same thing: Use national ranks, the data is sound, and here's the proof. Thanks for joining us in the "let the data tell us" group, at least for this discussion! |
I'm Newbie, and you're the data expert between the 2 of us for sure! But seems like the data sets you just posted actually do support the person who said Central doesn't finish last all the time, since in 2024 Central seems to have had a bad year and finished last in 3 of the 4 age groups they had (one being the 1st year they had 12s it seems); but in 2022 and 2023 they were almost never last, and Metro East who the same original poster who brought this up said was usually 2nd to North, that wasn't true either. I've got no dog in this fight, but it seems above you just said the data shows the person defending Central was wrong, which maybe is true for 2024 but based on the data you provided, can't at all be said to be true in the 2 yrs before that, where Central mostly were not last and sometimes were 2nd to Travel (actually they're 2nd to travel for 18s every year it seems - anyone know why that is?) Fascinating stuff! In the end though, all the national data in this thread says Central is a middling team among the Metro regional teams, and other than Travel being 1st, the only other "trend" among the 2022 - 2024 data is that North is usually 2nd. Lots and lots of moving around between the other 4 regional teams (East, Central, South PW & South FX). Ok now can I give you some questions related to my actual job (nothing to do with volleyball) and can you please do data analysis for me for projects? Your anonymous feedback is way cheaper than the consultant I use LOL! (Kidding, in case that's not clear!) |
Also, I will never know how you embedded a scroll-able data set into these fields... many here can barely embed their new comment in the right place and it ends up as part of the previous comment

You guys are really wrapoed up on rankings and stats.
And to the point of going down rabbit holes to boot. Does it really matter (that much)? I would have thought practice location, tournament schedule, and price are things to compare abd contrast? Logistics and all? Not nitpicking if Team XYZ North for Age123 is better than Team ABC South for Age456. |
Like any trend analysis the time period you choose is important to the analysis. Objectively it is fair to say the following: Over the last two years of club volleyball (2024 & 2025), Metro Central was the a) The region most likely to have teams with the lowest national rank of any of the Metro teams, b) Had the most "last place" finishes in national ranking when compared to their peer group, and c) Had the least amount of variability in the data (e.g. were most consistently the lowest ranked team when compared to other regionals except Metro North (who is equally consistent in being 2nd in the group). If you expand the time period to include 2022 & 2023, you can also credibly say that Metro Central's performance has: a) Declined relative to other Metro regions, and b) has a declining trend in national ranking between between 2021 and 2025. This declining trend has occurred at the same time the overall performance of CHRVA teams has been improving relative to the rest of the country. Posting the chart that shows the decline from 2021-2025 is hard in this forum, but if you scatter plot the rankings of all Central teams by year you will see that the best national ranking for any Central team has declined by about ~600 ranks and the worst national ranking has increased by around ~1700 ranks since 2022. Said another way, in 2022 the best Central team was ranked #1281 (U18) and the worst Central team was ranked #2443. In 2025 the best team was ranked #1818, and the worst team was ranked #4159. What you can't do is use the 2022 & 2023 data to skew the average performance of 2024 & 2025 in favor of the argument that Metro Central is actually in the middle of the pack against other Metro teams. 2 years is an eternity in club volleyball especially when the clubs in Metro Central's direct geography have been expanding. There were a lot fewer teams in the central DC Metro area in 2022 than there are today. |
100% those things are important. Discussing one thing doesn't mean the other isn't important. And none of this means the teams are bad or wrong or to be avoided. But if you've been around volleyball for a while you know that lots of parents are confused by the relative performance of a club "1" team versus another club "1" or "2" or even "3" team. Threads like these can help parents understand the complexity and make a more informed decision. |
| Omg who cares?! Just enjoy playing the game! |
You can do that at any level you play at. But you enjoy the game more if you play at a higher level. To get at a higher level, you need to pay attention to little things like coaching, teammates, results (and implicitly rankings). It's fine if you personally don't care - not everyone has to. |
