z Scores Intuitively
With a mean of 70 and a standard deviation of 10, we can calculate many z scores without a formula. A raw score of 50 has a z score of −2.0. A raw score of 60 has a z score of −1.0. A raw score of 70 has a z score of 0. A raw score of 80 has a z score of 1.0. A raw score of 85 has a z score of 1.5.
