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
