In Reply to: RE: The poll is trustworthy posted by racerguy on May 20, 2008 at 10:18:05
I just read the methodology and results too. Take a look at the first question which was "Which of the following devices do you own?" Respondents can tick more than one item in their response and 2 of the items listed are "Sony Playstation 3" and "A Blu-ray disc player". Note that the BD player item did not include the words "other than the PS3".
I don't think it's necessarily clear from the data table that PS3 owners without a separate stand-alone BD player didn't indicate "yes" to both items. There may well be overlap between the PS3 owners and the BD player owners.
Having said that, the data and report on the Harris Interactive site are a hell of a lot better and clearer than the report that AuPh provided the link to.

Follow Ups:
Your statements are ridiculous. The poll specifically included the PS3 in the hi-rez category ("Few report owning Blu-ray disc players (4%), Sony PlayStation 3 (5%), HD DVD players (6%) and the HD-DVD drive for the Xbox 360 (1% have external drive while 9% have an Xbox 360").
The poll even asked respondents if they planned to buy a "Sony PlayStation 3 which plays Blu-ray discs and Internet connectivity..." for crying out loud!
The PS3 can indeed play Blu-ray movies (and despite your assertion, that fact was clearly reflected in the poll questions), but its primary purpose is as a gaming console, and that is its primary target market. That's how most people think of it. When I think of a "Blu-ray disc player," I think of something like the Sony BDP-S300, which is targeted specifically at the Blu-ray video market. That's how most people think of it.
The PS3 deserves its own category, just like the other gaming consoles, which the poll properly reflected.
If the poll did not allow respondents to select more than one category of devices owned, your position would hold water, but that is not the case. You may not like the results, but you have yet to mount any sort of cogent argument against them.
Yes, the poll did ask if people were planning to buy a "Sony PlayStation 3 which plays Blu-ray discs and Internet connectivity..." but that wasn't asked in question 1 and question 1 did not specifically state that the BD player asked about was not to include PS3's. People answer questions in order based on the information in the question being asked and in previous questions. In Question 1 it is not clear that the BD player category excludes the PS3. They're asking about a lot of technology and people are as likely to answer based on what a product does as what it is, so a person with a PS3 and no other BD player may respond yes to both questions.
Obviously you've never done research which required the development of a questionnaire and the analysis of responses. I have, only once for a research project associated with a post graduate qualification, and believe me it's not easy to get a questionnaire right. You learn very quickly that if it's possible to misinterpret a question or make a mistake about exactly what is meant, some people will do exactly that. Questionnaire design is a lot harder than you think. These people were asking questions about a number of technologies including BD. It wasn't specifically a BD survey and that probably makes it easier for some ambiguity to creep into the questions.
I actually want to see BD be successful since I bought a PS3 as a BD player a couple of months ago and I'm prepared to live with that decision. My concern here is that I don't think the questionnaire was unambiguous in Question 1 and that makes me wonder about whether the figure for the total number of people polled with a device that plays BD discs is the sum of the number saying they had a PS3 and the number saying they had a BD player or whether there is some overlap in those 2 groups with some PS3s being counted twice and the actual number of people with players actually being lower than it looks. Given that I own a BD player I should be happy to add the 2 stated results together to get the highest possible number and not question them as I am doing. When I question the figures, I'm asking whether they actually put the total numbers for people with BD capable machines too high so don't say to me "You may not like the results". I'm actually suggesting that the numbers are less favourable for BD than the survey is suggesting and, as I said, I would like to see it succeed so it would actually be in my interests to shut up and not question the results in the way I'm questioning them if I wanted to take a really pro BD stance and ignore facts.

All assumptions on your part, all completely unfounded.
This was an online survey, not a list read over the telephone.

Obviously you don't know what you're talking about, because I've done this type of stuff more times than I can count. In fact I've done polls and surveys professionally, not just as a student exercise for a grade.
Harris has been in business since 1975, and has a stellar reputation. They know what they are doing. Forgive me for saying this, but you have zero credibility in this area. I'll take their conclusions about their poll over your assumptions about their poll, thank you very much.

It's been pretty clear why you don't like the poll results, and I can understand that - you are financially and emotionally invested. However, due to your bias you are offering an argument based on assumptions that lack foundation. It should be obvious to anyone without a dog in this fight that the poll was well-done, and if you weren't letting your bias cloud your judgment your student experiences should allow you to see that both the methodology and results are sound.
"This was an online survey, not a list read over the telephone."
So, do you think everyone reads the survey document from start to finish first, then goes back to the beginning to start answering questions? Most read the first question, answer it, read the second, answer it, and go on from question to question that way. Pretty much the same as answering questions read over the phone.
"Obviously you don't know what you're talking about, because I've done this type of stuff more times than I can count. In fact I've done polls and surveys professionally, not just as a student exercise for a grade."
Did you simply administer the polls and surveys, or did you design the questionnaires. They're very different things. As for my study, it ended up being published in a professional peer-reviewed journal so it was of an acceptable quality to meet professional standards.
"Harris has been in business since 1975, and has a stellar reputation. They know what they are doing."
I'm in Australia so I don't know Harris, and I'm not questioning their reputation, but no-one consistently delivers work of exactly the same standard in everything they do. Some things are always better than others and that's true for the best of firms as for the worst. I'm saying the wording of one question may lead to some people to report ownership of the same device twice, overinflating the result and giving a better result for BD than may actually be the case for the survey sample. I also said that they asked about players and not about whether the respondents with PS3s used their PS3 to watch BD movies. Some gamers may not watch BD movies and simply counting PS3s may give an overinflated result when it comes to considering them as BD movie players.
"It's been pretty clear why you don't like the poll results, and I can understand that - you are financially and emotionally invested. However, due to your bias you are offering an argument based on assumptions that lack foundation."
If I'm so invested as to want to discredit the results for that reason, why am I doing so in a way that would reduce the number of machines being used as BD players by respondents and actually make the situation look worse for people like me who have financially invested in BD? If I didn't like the results and wanted to argue against them because of my investment, I'd be arguing that they under-reported rather than over-reported the number of BD players owned by respondents. Your argument here doesn't make sense.

I'm so used to reading the emotional drivel from Blu-ray fanboys that I made a (bad) assumption about your motivations in questioning the results. Sorry.
As to the rest: I still believe your analysis of the poll methodology is faulty. And yes, I did indeed design several polls, not just simply administer them.
