he is using a group of data to describe a measure, but I am thinking the dimensions of a data are some variables that determine a data, it is just like the opposite. for instance, an experimental data could be determined by experimental temperature, time, etc.
i know what you mean, but what about this: you count the cars sold in 2008 and the cars sold in Toronto, separately, then you put all data together and extract the data for cars sold in Toronto in 2008, so this number is determined by time and location. if it is not right, i guess i've totally messed up
