1. Practice converting raw scores into z scores:
What would your z score be if you were part of the original study?
x = (your score)
M = 21
SD = 7
𝑥−𝑀
𝑧 = 𝑆𝐷 =
2. Practice converting z scores to raw scores:
For someone with a z score of 0.5, what would their raw Math Anxiety score be?
Z = 0.5
M = 21
SD = 7
𝑥 = 𝑧 ∗ 𝑆𝐷 + 𝑀 =
3. Let’s pretend we want to convert Math Anxiety scores to scores from a standardized
distribution with M = 10 and SD = 2. What would your score of become in the new standardized
distribution?
𝑥 = 𝑧 ∗ 𝑆𝐷 + 𝑀 =
4. Keep practicing by comparing your score to your classmates.
