Mean, median, mode, again?

Is it just me or does it seem like we have been talking about mean median and mode for FOREVER in this class? I guess it could be because we started before Mardi Gras and just finished up with it (hopefully) today. I feel like ch. 4 could have been much more interesting had S&R actually given some more examples of the usefulness of the more advanced mathematical techniques. Right now it seems like there is an innundation of concepts with little practical focus. As I say this I know I am going to get to the homework and that will be a big help, but moral of the story is I am very much looking forward to moving on and getting down to more of the dirty work and less of the conceptual algebra.
