I don't mean to come across as a stat software expert, but I do have a fair
amount of experience with a number of packages, especially SAS,
StatGraphics, JMP, and MINITAB. I find MINITAB very easy to use. My

ny: this is a designed as a really easy question to o test your
understanding of different "averages", whichever are discussed in
your textbook: mean (that is arithmetic average), median,
apparently, midrange, whatever else (see your textbook). but keep in

A LOT depends on what kind of analyses you wish to do with the software, the
capability level of the user w.r.t. statistics, AND the frequency with which
you'll use the software (related to "relearning" how to use the software
after an extended absence).
I've used a bunch of software in my day. I

You have not given the entire question, but I would guess the
motivation behind it goes something like this: You have been shown
many measures that might be called an "average"--mean, median,
midrange, mode, and so on. You are presented with some artificial
data for different makes of cars. Acc
