Survey on Media

Let's say if I'm asking which source you often use to get information. Newspaper? Radio? TV? And the survey shows 62% of the people chose the internet. You might be thinking I am going to say, how important the internet is, or how quickly it has changed the world for a few years. But what if I tell you this survey is conducted on the website globalandmail.com? Our answer will be different because the people who did this survey on a website must be frequent users of the internet. This sample is a biased sample. So we have to pay attention to how a survey is conducted.
