I had to do a brief presentation in my class tonight about statistical analysis: an overview of mean, median, variance, standard deviation... and I threw in a bit about z-scores just for fun.

I set up a quick PowerPoint presentation to go along with it. Into this PowerPoint slideshow I managed to include: Jack Webb as Sgt. Joe Friday; the devil; Zorro; Ghostbusters (very pertinent, this reference); B. F. Skinner; the alien Exeter from This Island Earth; and Canadian speller Leslie Newcombe.

I can't say I had 'em rolling in the aisles (or "isles," this being Hawaii and all), but the expressions of vacant-eyed astonishment were even better than mere amusement.

I am obviously very tired. I need to get up early so I can change the tyre on my car before going to work. After work, I shall have to purchase a new tyre for my car.

Do Canadians spell "tire" as "tyre," or is it a Britain-only thing? I experienced a flat tyre in Britain once, due to an encounter with a curb at a roundabout. Having it repaired was one of the more interesting "local colour" highlights of the trip.

I can't believe it's only Monday.

P.S. -- Fun Stuff In The Mail!!!!
