... ask what the probability of "1/6" is, because the answer is always 0... Rather, we ask what is the probability that the value is in the interval (a,b). So for continuous variables, we care about the derivative of the distribution function at a point (that's the derivative of an integral). This is ca ...

Using SAS® to Create an Effect Size Resampling Distribution for a Statistical Test
... That is, the sample mean differs from the hypothesized mean by more than ½ an observed standard deviation for a medium effect size. For assessing clinical/operational significance the effect size is more meaningful than the p-value which is strongly influenced by the sample size. Note that in the on ...

... No matter how well a study has been carried out or how carefully the data has been collected, there will always be some uncertainty as to how accurate our conclusions are. This is simply due to the fact that we have taken a sample of subjects, rather than recording results for every possible subject ...
