Guest guest Posted February 22, 2012 Report Share Posted February 22, 2012 What about sensitivity n specificity?ThanksOn 22 Feb 2012, at 13:09, "rpmk17" <rpmk17@...> wrote: Asa! Well a T test is usually conducted to see if a difference in between two samples is statistically significant when tested for one variable...my understanding is that if we take 2 samples for example males and females and see a variable like for example caries(variable can be anything)...and we want to see if there is any statistically significant difference in between the two...then we will do a T test.For this we make a hypothesis(supposition).It may be like yes males and females have same caries incidence no(null) males and females do not have same caries incidence. Percentile is less confusing:) When we say we got 80% marks or 80% of children have caries then that means 80 out of 100. But when we say 80 Percentile it means that our marks are 79 or 80 percent more than the people who sat the exam...or in other words 80% people had less marks than us.Now the total number of candidates can be anything. I hope these makes sense.Feel free to correct me if I am wrong since I am no expert on stats:D > > > HI ALL > > I have been through statstics but can`t properly understand either the: > > 1. student T test or the 2.

Guest guest Posted February 23, 2012 Report Share Posted February 23, 2012 As much as I hate stats:P...but ok...so sensitivity is according to definition number of true positives that are correctly identified by a test and specificity is the number of true negatives identified by a test....so its better for a test to be sensitive rather than just specific...sensitivity of a test is the probability that it will surely give us a positive result in the end when we compare it to a gold standard.For eg if drinking sugary drinks is proved to give you caries then a test in which we give children who don't brush their teeth sugary drinks is a test with high sensitivity...meaning it has a high likelihood of giving us a positive result....something they call true positive(the patient has caries and the test is positive) On the other hand if you do a test in which you give children sugary drinks but the children are brushing their teeth and have a good oral hygiene...then there is a high likelihood that the children wont get caries...this means that this test has high specificity meaning the test is producing a true negative result(the patient does not have caries and the test is negative) when tested on a sample which was initially normal. So I think that would mean sensitivity is inversely proportional to specificity. So sensitivity is the prob that a test says that a person has the disease and when we do the test/experiment we find out it is fact that the person has a disease. Specificity is when the test says the person doesn't have the disease and when we do the test/experiment it is a fact that the person doesn't have the disease.
