My state’a standardized test says kids are “at risk” if they aren’t in the top 40% of the test. The top 50% could all be traditional “a-b” students. But because they weren’t in the top 80% of a-b students they are at risk for failing academically… It’s so asinine and disheartening. The last half of the year is devoted to this idiotic test. Kids could be learning stuff that will enrich themselves… Instead they are learnig how to take a test better.
I was skeptical of these numbers until I did the research. It’s even worse than I thought. Did you know that only 20% of students test in the top quintile? Is our children learning?
One could construct tests where this isn’t a given. Create an exam with one really easy question and one really hard question. You’ll end up with a huge spike in the center and two tiny tails. The top quintile of correct answers (<=1.6 correct answers) will be vanishingly small.
Yes. In a normal, or Gaussian, distribution, the data is symmetrically distributed around the mean and thus mean (average value), mode (most frequent value) and median (middle value) all fall on the same point, which is the highest point of the curve.
Consider an exam in which there are two questions: one very easy and one very hard. You’ll get a supermajority of people who answer the first question and two tiny tails - zero correct, two correct - such that the mode is very high and the outlayer groups are very small.
Then well over half the people are in the median and mean.
True, but those who know what “median” means probably also know what a “quartile” means, so if I used “median” it would’ve made my comment less of an “obvious, duh!” thing and spoil the unstated point I’m making as well as the joke.
Best leave the mathematical incorrectness there to preserve the feeling of obviousness.
I can almost see a facebook post along the lines of: One doesn’t have to be a rocket scientist to understand how terrible things are, when fully 25% of the population are in the bottom quartile.
Everyone should be in the top! Everyone should have unlimited resources from disabled addicts to military bioweapons developers - it should be a flat line, a plateau!
Bioweapon developers should be shot in the street. Disabled addicts should be provided the proper help they need; and the education should be changed so there are less disabled addicts and bioweapon developers alike.
