The key is the use of statistically derived random sampling procedures. These ensure that survey results can be defended as statistically representative of the population. Surveys that do not follow these procedures can produce results that lead to misguided market research‚ strategic‚ or policy decisions. Any so-called "survey" in which no attempt is made to randomly select respondents‚ such as call-in readers’ or viewers’ "polls"‚ is likely to produce results that in no way reflect overall public

Separation of Mixtures Mixtures exist in many forms in the world‚ and if it were not for methods of separation‚ many of these substances would be meaningless to us. Separating mixtures is extremely important to human lives; for example‚ many people filter water so that it is safe for drinking. Mixtures contain two or more substances that are not in a fixed ratio‚ and while some mixtures‚ such as concrete‚ are useful‚ others including salt water‚ are not as useful to us. Filtration‚ distillation

Mixtures and Solutions can often become confusing because solutions are mixtures‚ but not all mixtures are solutions. A mixture can either be homogeneous or heterogeneous. A homogeneous mixture is where the mixture’s components are distributed uniformly within the mixture. A heterogeneous mixture is where the components are not uniform. Mixtures can either be miscible or immiscible‚ the difference being whether or not the mixture forms a homogeneous mixture or not. In a solution a solute is soluble
