This looks like another fun thing to do, so why not?
The prompt this week is “average.” Another word for the average is the mean. Calculating it and the standard deviation are the first two things you learn in statistics classes. Shan already talked about the bell curve, so I’m not going to bother with that.
I always had average grades in high school and college, after having been one of the top students in grammar school. Drove my mother nuts. “Why are you getting so many C’s, Johnny? You got all A’s and B’s in grammar school!”
In high school, we were assigned a level based on where we were placed. The higher the level of the class, the more a grade of C meant. If you were in a 3-level class, your grade was multiplied by 1.2, so a C (=2, B=3, A=4, D=1, and F=0) was more like a C plus. In a 4-level class, your grade was multiplied by 1.5, so a C was like a B. An AP class gave you a multiplier of 1.8, making a C a B plus or A minus. So, my raw grade-point average might have been 2.0, but the weighted average was more like 3.2.
Hey, it got me into Northwestern.
When I got there, the letter grades weren’t weighted, so my GPA was a little above 2. But, given that Northwestern was such a good school (HA!), a C there was like a B everywhere else. So really, it’s all relative.
Well, kinda. My grades were indicative of the fact that I really didn’t care. I was unusually bright (according to my mother), and maybe that saved me.
Saved me? Weird… Saved me from what? Bad grades? They really don’t mean anything once you’re out of school. It’s a game. “I got five A’s.” Great! Want a cookie?
Really. C is average, meaning the work you produce is average relative to everything else. That’s the way school thinks. If ten kids get A’s and B’s, ten have to get get D’s and F’s. Everyone else gets a C. Remember when you used to ask, “Are you going to grade on the curve?” That’s the curve.
If you were to plot intelligence against grade-point average, you’d probably get a weak correlation between the two. They know that. That’s statistics. It’s all based on statistics.
How’d I di?
