These two numbers represent the "true" value for the skewness and kurtosis since they were calculated from all the data. In real life, you don't know the real skewness and kurtosis because you have to sample the process. This is where the problem begins for skewness and kurtosis. Sample size has a …... Skewness will be positive or negative depending on the weighting of the distribution and kurtosis will be positive and the larger the magnitude the tighter the distribution about the mean. I hope

- That is, if you want to know something about the kind of sample mean you might get (such as the probability of its being between 1.0 and 1.4), the normal distribution (with the right mean and SD) will give you approximately the right answer. This is a big step, because the only other way of getting any kind of answer at all is via simulation.
