SAT stats

Re “It doesn’t test for success,” Opinion, March 13

I took a statistics course in college a few years ago. The instructor informed the class that, statistically, the SAT exam has only a 3% probability of predicting success in college, and this with a 5% variation either way. In other words, it is totally useless. He asked the class why we thought it still exists. I answered that it is a big business that a lot of people make money on. He agreed. Joanne V. Creighton’s article only confirms this.
