statistics for dummies

January 27, 2010

Thanks to all my visitors from wow.com who left comments on various posts. One thing that came up in a  couple of places is the suggestion to use more powerful statistical techniques on the data. Great idea! Unfortunately I took my last stats course at Queensland University in the first semester of 1978… and no, that’s not a typo… and I’m sure things have moved on a bit since then.

So I’d like to issue an open invitation to anybody who does have the time and the statistical skills to help play around with the data and see what we can come up with. I’m happy to have guest posts here, with the proper attribution for you, or you can post on your own blog.

We’ll have to see how to handle access to the data, but I’m sure there’s somewhere in cyberspace that’ll help with that problem.

Just leave a comment here. Your email address stays unpublished but I can see it and I’ll reply as soon as I can.

appetite for destruction

January 11, 2010

… seems to be running at about 4%. But more on that in a second. I’ve updated my Google App Engine site for patch 3.3. Some of the twink reports are a bit iffy because of the small sample size so I’ll refresh them again next week when I’ve got more data. Not a lot of people playing level 59 twink Shaman, it would seem.

Meanwhile, I’ve added a couple of new general reports, including the ever-popular class distribution table. This time, I’ve added a view of the overall popularity of the 3 talent trees within each class. Note that the percentages for each tree are based on the total level 80 population and not on the count of the class. Destruction warlocks are 3.9%, which means 3.9% of all level 80 toons are destruction warlocks. And the query is based on the active spec, where the toon has dual specs. I’m hoping that, statistically speaking, the sample is playing with their preferred spec.

Class Popularity Tree 1 Tree 2 Tree 3
Paladin 15.4% Holy:

4.2%

Protection:

4.8%

Retribution:

6.3%

Death Knight 14.0% Blood:

6.1%

Frost:

3.9%

Unholy:

4.1%

Druid 11.5% Balance:

2.9%

Feral Combat:

4.1%

Restoration:

4.5%

Priest 9.8% Discipline:

2.7%

Holy:

3.4%

Shadow:

3.7%

Warrior 9.4% Arms:

2.9%

Fury:

2.6%

Protection:

3.9%

Mage 8.7% Arcane:

4.0%

Fire:

2.2%

Frost:

2.5%

Shaman 8.4% Elemental:

2.9%

Enhancement:

2.0%

Restoration:

3.5%

Hunter 8.1% Beast Mastery:

2.1%

Marksmanship:

2.2%

Survival:

3.7%

Rogue 7.4% Assassination:

4.1%

Combat:

2.8%

Subtlety:

0.5%

Warlock 7.4% Affliction:

2.1%

Demonology:

1.4%

Destruction:

3.9%

So we have the retribution pally as the most popular at 6.3% down to the subtlety rogue the least popular at 0.5%.

Comparing this to what we had last time, the most notable thing is the decline of the hunter. Paladins and DKs continue to rule. And not a lot of love for the rogue or the warlock.

This sounds kinda ominous… Meanwhile I’m just cranking out new reports for patch 3.3. Should be up by early next week.

blog status

December 31, 2009

I trust everybody had a happy Christmas; I certainly did. Unfortunately, the post-Christmas weather down here has moved into what I call the “traditional Christmas heatwave” – a few mad days that seem to arrive pretty much on time each year now. I sure hope there is no such thing as global warming; I’m not going to like it one bit, if this is a taste of the future.

Its 38° outside (no, that’s Celsius; 100° F) so I’m hiding indoors until it blows over. A perfect excuse to update the site so I’m scanning the armoury now for patch 3.3 data. Looks like there have been no significant changes to the XML (not the bits I use, anyway). I should have enough data to start updating the reports in a few more days.

dances with patches

December 14, 2009

I’ll be updating the data for patch 3.3 in due course. There’s a lot of class changes, so we’ll give it a couple of weeks to percolate through the playersphere. But there’s nothing much new in the XML that I can see, unfortunately.

There are also hints of interesting new armoury features to come. I’m not sure that very much can be datamined from them, but character activity notifications via RSS may hold real possibilities.

Meanwhile I’m working slowly through a to-do list based on your requests and suggestions. I’ve got an economics page up over at my Google site. I’m adding consolidated reports – ie across the total population – on the most popular gems, glyphs, enchants and crafted gear. I’m also looking at a similar set of reports based on my twink samples – that’s where some of the big spenders are so it would be interesting to see an overall picture of where the cash goes. They’re not spending up big on Haris Pilton bags, that’s for sure.

a scan darkly

October 14, 2009

I’m doing a fresh scan now, so I should be able to update my reports in a week or so. I must admit I’m not following patch 3.3 all that closely, but if it comes along then no biggie…

patch 3.2.2

September 24, 2009

Just a quick note to say that I’m not gone… Things are quiet here for various reasons – one of which is that I’m taking a break from playing the game. But I’m happy to keep these sites going and to keep them up to date.

I’m fully intending to update my reports once patch 3.2.2 has had a bit more time to work its way through the system.

And I’m working on a new set of reports, using a different database technology, that may end up producing interesting results. No promises on when we might see those results, but we’ll get there in the end.
