In Lectures we discussed skewness. There are a number of definitions relating the mean, median and the mode to skew. If you're interested, here is a link to a journal article:

Notice that when in Stata you can find out the skew of a variable by using the command
summarize (varname), detail
If it's positive, the values are skewed to the right and vice-versa. Zero skew means a normal distribution.
