Normal distribution of sat scores
WebA student has taken both tests. They scored 600 on the SAT-Math and 22 on the ACT-Math. Which score is more impressive? We can't directly compare the student's SAT and ACT scores because they are on different scales. We can convert these test scores into z-scores so we can directly compare them. \(z_{SAT}=\frac{600-500}{100}=1\) WebIn the example above, we saw that SAT scores follow a normal distribution with a mean of 1100 and a standard deviation of 200. How high are the top 2.5% of scores? We know that 95% of SAT scores are within two standard deivations from the mean, so 5% are …
