Let’s say if I’m asking which source do you often use to get information. Newspaper? Radio? TV?
And the survey shows 62% of the people chose 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 global and mail.com?
Our answer will be different. Because the people who did this survey on a website must be frequent users of internet. This sample is a biased sample.
So we have to pay attention to how a survey is conducted.
