What about changing it every hour? Then you have sufficient randomness over
time, and no flashy buttons.

 Yes, a sequential run does introduce various problematic biases.

 An IP-address based hack could work, but would need to take into
 account dynamic IP addresses and such, without introducing strange new
 biases of its own. We'll discuss a bit further - good ideas /

 You still have the problem that peoples response to future buttons
 will depend on the past buttons they've seen.

Yeah, I'd suggest it is better to show each person one button type and
stick with it.

One can approximate that behavior either by assigning each user
randomly and tracking their type via a cookie or by selecting based on
higher order bytes in the IP address and assuming those are fairly
stable (e.g. using BBB mod 4 where the address is AAA.BBB.CCC.DDD).

Neither approach is foolproof or totally without bias, but one can do
fairly well.

Donate Now Keep Wikipedia free for everyone.

Is no one else concerned by the use of the word free in the message options 
being tested.  I wouldn't want these ambigous messages like these on the site 
no matter if they beat out the no message option by 10 to 1.  Why can't we test 
messages that are actually clear and honest?  Wikipedia will still be free for

[Foundation-l] Donation Button Enhancement : Part 2

2009-07-20 Thread Rand Montoya
Wikimedians--

As many of you know, last month we began work on exploring the 
visibility of the donate button on all Wikimedia projects. After a long 
comment period, we received many comments and many new ideas. Some of 
these ideas we have incorporated into a new set of test buttons. Thank 
you to everyone who took the time to evaluate Round 1 buttons. You can 
see those discussions here: 
http://meta.wikimedia.org/wiki/Fundraising_2009/Donation_buttons_upgrade/Round1 


We have 4 designs that we will be testing on the Wikipedia:EN main skin 
during August and the first part of September. We are going to evaluate 
each button for one full week. This process will unfold over the next 
two months.

You can see the designs and timeline at this link:

Testing should be done in parallel, not in sequence.  History has
demonstrated that donors have a tendency to respond disproportionately
to the new thing.  Which means that whatever button you test first
will have an advantage over whichever one you test last.  Probably the
easiest way to get a reasonable distribution is to vary which button
people see based on their IP.

It's also necessary to control for seasonal traffic (and thus donation)
variations. I note that the first three button tests are at the end of
summer while the fourth coincides with the beginning of the school year. It
could be the case that there is no variation, or that the variation is
highly significant. Since nobody has looked there is no way to tell if the
test results are valid.

Or simply to randomise it entirely.

If either of those aren't possible for technical reasons, it might be
practical to rotate them - run each button for x many hours at a
stretch, rotating them so as to ensure they don't regularly go up at
the same time (of the day or of the week) and so that they get roughly
equal coverage.

For this the normal procedure is to give users a session cookie of
some kind (either one handed out by the server or one just generated
on the client)  and base the selection on that.

For caching reasons I suppose you'd just want to do this all client
side. Should work fine.

Alternatively, someone rigs up the front end caches to do this
substitution based on IP at serving time. This would be non-trivial
with squid. It would be much easier with varnish, alas.


In any case, I strongly agree with the argument against running them
sequentially. Not only do you get the uncertainty from changing habits
over time but later buttons will suffer from the influence of prior
ones. Whatever can be done to avoid sequential testing should be done.

Didn't we do this kind of trial during the last fundraiser - with the
messages at the top? They were rotated each new day weren't they? In any
case, whatever we worked out for last time can't we use that method again?
