What is the Level of Significance and how do I figure out what it is mathmatically?
the level is a chosen level to give your answer real validity or not. For most stats in medical research a 95% level is chosen. In other words there is only a five percent chance that the result is invalid. This is signified p %26lt; 0.05. If you have a result from a sample size of three: eg my 3 friends all eat chesseburgers therefore everybodsy eats cheezeburgers. Look up the tabel of significance values at it will tell you a sample size of three gives you a significance level of about p %26lt; .90 in other words you have only a ten percent chacne of being right and 90% chance of being wrong! If you have a sample of 1500 US people and you find that 70% of them eat cheesebrugers - because of your large sample size your result is likely to be valid at the 95% level of significance; ie at p %26lt; .05. so you can say with confidence that about 70% of all US people eat cheesburgers. Hope this helps.What is the Level of Significance and how do I figure out what it is mathmatically?
