Chapter 5: Standard scores and normal curve



1. Standard score (z-score)






2. Normal Distribution

3. Calculations using the normal curve



A. Given a raw score, what percent of scores fall below that score?







i. Draw diagram--draw a normal curve and draw on it

a. the mean,

b. the raw score

c. an arrow with the direction





ii. Use the Z-score equation, to solve for z.

iii. Go to table to find area under curve.



4. Given a percent area, what is the raw score?



1. Draw diagram

2. Use table to find z vs. Area (cuz we know it)

3. Use equation to solve for X
