Solution
Never impossible. At least in terms of audience. Old people and "adults" did not consider. So anyway, Putin.
Here is more like "the results of the online survey, 100% of the population has Internet" ☺ - Timmothy50 commented on October 8th 19 at 03:11

Reformulate the question. Are the events "took part in this poll" and "vote for such and such candidate" — independent? Probably not. There is a whole science — sociology, which, in particular, and examines how to do these surveys that the events really were independent.

immediately half of voters under the age of 18, so of course not. The more the audience is quite narrow.

No, you can not. Find out the number of able-bodied people in Russia, calculate what percentage of respondents Vkontakte are from them and get the ratio of how true or not )

Representativeness — matching characteristics of the sample the characteristics of the population or the General population as a whole. Representativeness determines how possible to generalize the results of studies involving a particular sample to the entire population from which it was collected.

Also, the representation can be defined as a property of a sample population to represent the parameters of the population, significant from the point of view of the objectives of the study.

When you consider the appearing, recently, the facts of the mad botovodstva Nashi, no one voting in the VC do not take on faith. Only perhaps with an error of "plus or minus half the bucket".

And that the survey was representative, it is necessary to take how many there % of the population
country in an equal proportion of population, by age and sex in each region to interview.

In this case, the survey can be signed "in the opinion of the users on the network Vkontakte.ru"

Of course not. And the poll unrepresentative. Although it depends on what you want to achieve, of course, and that using it to learn. This sample is representative for the survey, "who you voting for visitors of Vkontakte from Russia over the age of 18", there will not argue.

This representativeness is not determined. You can choose 0.1%, the sample will be representative, and the essence of these surveys and the complexity of the selection of the sample. In this case the situation is reversed — even if we said 50% of able-bodied people of the Russian Federation, the survey would not be representative.

Still very far from the moment when the Internet will cover equally all segments of the population.
