Opinion Polls and mathematics

Opinion surveys and mathematics.
Sample surveys are the application in a specific area of certain mathematical, in particular of some of the mathematical theory of probabilities procedures or statistical mathematical research.
This are some assumptions based on the assumption that certain operations can be performed with numbers can perform when mathematics no longer pure and becomes applied and represents aspects of social reality.
Made them, is supposed to be possible to measure a specific social aspect, the intensity of the positive image of such candidate, or measure the views in favour, against and indifferent about a specific problem.
Is that the applicability of the procedure of the survey is based on accepted an isomorphism between mathematical properties and properties of social phenomena. Once assumed this, you can use methods and techniques (sample, designs for example) appropriate to establish which is the best way to learn about a certain aspect under investigation.
These methods are standardized and validated, as they are all scientific procedures procedures. It is important to remember that a survey seriously is apply a background of theoretical and methodological knowledge to a social research.
