There are no complaints. We have all happy customers everywhere. Satisfaction bellows from chests of our customers riding forth in our system.
I was so pleased with Metro's service that I bought a new car and now get to work for about the same price daily! And MUCH more safely and timely I might add!

I'm reading through the methodology now and I've already found several problems (I'm only on the fourth page). The sample size alone says it all; 385 bus customers, 385 rail customers. Selection was based on state using random phone numbers.
DC VA MD
RAIL 34% 33% 33%
BUS 59% 17% 24%
That doesn't seem so bad, right? Here's the fun part: "21% of calls were cell-phone only households---known to be younger, more urban, lower income, and more likely to be Black or Hispanic." Now, lest anyone make the dumb "oh, it's racist!" claim, taking into account existing demographics is a part of good surveying. That said, this 21% figure is insanely low.

In addition, any good survey requires you use different methodologies. I'm no statistician, but I do know that you always want to have data collected in different ways. People are generally more willing to give metro the benefit of the doubt when they are comfortably at home than they are when, say, waiting for a Rush+ Blue line train.
I'm about as "satisfied" with metro's services as I am with Dr. Gridlock's reporting....
A good survey report should include the questionnaire (completely missing), sample info (which they have, sort of), the data collection strategy (sort of present, but some major omissions, e.g. time of day calls were placed), and the data analysis strategy (pretty much done). So this report is pretty crappy. The 770 customers they surveyed is probably a sufficient sample size for the 1m daily ridership, so they got that right at least. But the full report is missing a ton of information. They only present positive statistics. In a normal survey, you would expect to at least see a couple areas of weakness. Note the difference between rail and bus questions. They mention the high reliability score for bus but say nothing about the straight reliability score for rail, only including a composite index. That means they probably weren't too proud of the reliability score. They do not include any information about the questions they asked, which is a really bad sign. For example, their reliability question could have been "Would you say that your trips on metro rail goes well more often than not?" I would say yes to that. But that really means that my service is more than 50% good, which I would hardly consider a fair measure of satisfactory. And who the hell actually responds to phone polls anymore anyway?

Couldn't agree more. I was pretty amazed that none of the questions were released, though I'm sure you wouldn't be able to stall a Freedom of Information Act request for any of this information for too long. I'd love to throw in such a request and see if Metro refuses.
Are these the surveys they were handing out in Metro stations? If so, I happen to know they were very selective who they gave the surveys too. I WATCHED on two occasions Metro employees handing surveys to people as they went up escilators but holding their hands behind their backs and not offering surveys when white people came by.

They also carefully guarded the survey drop boxes in stations, no doubt so they could open the box and throw away surveys from people who "looked" like they'd give a bad survey.

You can be SURE this data has been massaged and tapered with.

That's OK; it'll work for then about as well as the Republican "weighted" polls worked for them. It'll give them a false sense of security until the next accident -- and until federal authorities finally get involved.

When do you expect these authorities to save you/us?
This was not the in-person survey. It was conducted over the phone. You may be right about the massaging, but there is no way to know without the raw data and questionnaire.

So we now know where the Unskewed Polls guy works.
This survey was clearly a PR move, not something that WMATA is actually using to improve service. Asking someone a vague question like "Are you satisfied with Metrorail service?" does not get into enough detail to tell you anything useful. If you asked me "Are you satisifed with Metro service?" I'd probably say yes, overall - I use Metro mostly for commuting, and it gets me where I need to go in a (mostly) dependable fashion. And obviously I recommend that my out-of-town guests use it, since even with all its flaws it's still far easier than driving around DC and trying to find parking.

Now, if you were to ask me any of the following:
"Are you satisfied with night and weekend Metro service?"
"Are you satisfied with the cost of Metro?"
"Are you satisfied with the business operations and leadership of WMATA?"

my response would be a resounding HELL NO. But of course they aren't looking to get this kind of feedback.

"Asking someone a vague question like "Are you satisfied with Metrorail service?" does not get into enough detail to tell you anything useful."

Sure if does! If the results are resoundingly positive, continue with the status quo. If, however, the results are less than perfect, it's time to unleash the number-massager (no need to actually improve-just fit the requirements to the performance if it can't be spun).
Did anyone here receive a WMTA survey via e-mail earlier this week? I got one on Monday. The questions and rating instructions were very poorly written. Having taken data analysis and survey formulation classes in grad school, I'm sure my professors could have used it as an example of what NOT to do. Figures..it's Metro after all.
I am glad that Metro spent money saying that Metro is good to customers of Metro.
