A common example is the log-normal distribution. A result of the central limit theorem is that these arise in quantities that are products.

A nice example for many purposes is the beta distribution — like the normal distribution, it only requires two parameters to define it.

The opposite of a skewed distribution is a symmetric one, for example the normal distribution.
