YouTube can definitely be a valid source depending on the channel and what you're looking for. For instance, many companies and organizations do use YouTube to make announcements and various other videos. In fact, the U.S. Governement also has a YouTube account, which would probably mean that YouTube has at least a couple of credible sources.
A source is considered valid if it has these qualities: 1. It is not any type of forum 2. Answers cannot be modified by the public 3. It is not a personal website A lot of people look at Wikipedia, YahooAnswers, and even this site as invalid sources.
I'm not sure what you're asking here. Are you talking about validity?.. And if the measurements you have provided are valid?.. Or Reliability.. If the measurements you have gotten are reliable as you can check them with another source and you get the same answer?
No, the scientific method can be uncontrolled to for it to be valid.
a valid investigation is an effective investigation i think. The results turn out to be what you had inferred.
No, YouTube never has been, nor is today a scamming website.

No, YouTube is not open source. You can, however, access YouTube's API information should you want to develop an application for it.
Maybe you already have a YouTube account. If you are sure don't have one, then create an alternate email for use.
It means that the web address isn't valid, or correct.
It is valid but it is reserved as a source address only by RFC1700 standard.
That depends on who answers the question and how well they support their answer.
It depends on its content, obviously.
Always check another source to make sure what is being presented is accurate and valid.
Google does not allow the upload of background images on YouTube profile pages anymore. Only the header image and background color is changeable.
you can get this app called "iwoopie" and that lets you save videos from youtube onto that app, then you can later view them without a valid internet connection. :)
Any citizen of a country who is above 18 years of age, has a valid source of income and tax payer ID can trade in stocks. People without valid Tax payer ID or a valid source of income will not be allowed to trade in the stock market.
Any valid file name is a valid name for a C source file. The extension itself is immaterial; it is part of the file name and only serves as a means of organising files. The extensions .c and .h are merely a convention. You don't have to use them if you don't want to, but it makes sense to stick to the recognised conventions, particularly if you intend to distribute your source.
