Which is more typical median or mean?

For some kinds of distributions one, for others kinds, the other.


Are all symmetric distributions normal distributions?

No. There are many other distributions, including discrete ones, that are symmetrical.


The usual sampling distributionof the difference between means is a what?

There is no such thing as "the usual sampling distribution". Different distributions of the original random variables will give different distributions for the difference between their means.There is no such thing as "the usual sampling distribution".

Is the beta distribution is a special case of dirichlet distribution?

In a sense.Beta distributions are the marginal distributions of the Dirichlet distribution.


Why do data distributions take a particular shape?

If you plot data they must take some shape (or another)! Data distributions can take all kinds of shapes. The only constraints are thatthey cannot be negative andthe integral (sum) over all possible values is 1.The shapes can be flat (uniform distribution), symmetric (uniform or Gaussian), asymmetric with one peak somewhere in the middle (Poisson), asymmetric with a peak at an end (exponential). These are examples of different shapes that are attained by common continuous data distributions.
