Hi, I am the CRS database administrator. I'm pretty sure that the CRS and SIBS databases can be multiplied, but I know for sure that there is NO WAY the DATA/DATUM can be averaged ! ;)
As I'm in the middle of the most boring psychology assignment I've ever had the misfortune to stumble across, complete with converting Pearson's R to z scores in order to compare them to another score (unofficial that was designed by the Psych dept) from an unrelated test that has nothing to do with the other two (no I'm not kidding), this treat of a strip is just in time!
I bet all you people who are arguing about the usage of the word "data" also argue that 2001 is the true millennium.
"DATA" is the plural of DATUM, but it is also considered singular when used as an abstract mass noun along with a singular modifier such as "That" or "This". The usage in this comic is grammatically correct.
Engineers might not catch the difference, but English majors will.
