In Statistics a Standard margin of error of 5% (Put in other - TopicsExpress



          

In Statistics a Standard margin of error of 5% (Put in other words: Confidence level of 95%) means you are almost 100% certain that the thing will happen. Now you are saying this research had a margin of error of 3.6%? The researchers must be too confident. What gives them this level of confidence when the sample is not representative (another principle in Statistics) enough? 3000 sample against a population of 7, 500, 000 is almost 0.0%! What sampling technique did they use? These, plus many more, questions leave many confused as to the credibility and validity of this research! Somebody help me...........!
