In the Geostatistical Wizard's variography page, you can see that values correspond to the parameters on the right.
There are various export options on the variography page in the Geostatistical Wizard. You can output the red dots (binned values), the blue crosses (averaged values), and averaged values using geometrical intervals (you don't see these in the semivariogram graphic, but they are the values that are used in our weighted least-squares algorithm to fit semivariogram parameters). The main reason to export is that you can graph the semivariogram in another program like Excel, where you have more control over the graphic (like changing colors, labels of axes, etc).
You can also export the Semivariogram/Covariance map, either as a raster of weights or a raster of values (where the value is either the semivariance or the covariance, depending on whether "Variable" is set to Semivariogram or Covariance).
