On the Other Hand...
The classroom was designed to hold 24 students. We don’t count the teacher or his desk, yes, his desk. He taught high school math. This was not the brainy class, just your basic, shall we call it math for non-math majors? Most of these young people would not be taking the SATs. They would find jobs, right after graduation.
His job, as he saw it, was to help them balance a check book and plan to live on a budget. His classroom had 24 desks for 24 students. While at that time in history there was no particular sensitivity to what we call politically correct, the chairs seemed to be ahead of their time. They served all who would sit in them without bias. The only consideration that those who ordered student desks had was in having the correct percentage of left and right desks. It was a math problem. It was a real-life math problem.
If the general population is half male and female and if a greater percentage of males are left hand dominant, how many left-hand desks should you order for a classroom of 24 students? Just tossing out numbers, the general population is estimated to have between 8% and 15% who write with their left hands. Of the 24 students it might be expected there would be a need of between 1.62 and 3.6 left-handed desks. So, do we round up or down? Each school year he began his math lessons with the same problem.
Each school year the statistical expectations never matched the smiling faces in his classroom. He taught six classes. The desks remained constant. Some students who took notes with their right hands had to sit at a left-handed desk and vice versa. In the real world the sample rarely fits the statistical expectation. Like a final puzzle piece, you have to turn it just right before it fits into its slot.
