Week 8
1. Topic: Mean and Standard Deviation with Probabilities a. Expected value and Risk i. Definitions 1. Expected value is mean
2. Risk is Standard Deviation
ii. KEY TERMS 1. Random variable I. Quantitative result of an experiment that can 
control by chance
II. More detail (sentence) 2. Discrete Random Variable: Finite number of  countable classes 3. Continuous Random Variable: Countless Number of  Values 4. Discrete probability distribution I. Total # of observations of a given outcome / 
total # of outcomes
b. Special Terminology i. Expected Value 1. Calculation: Sum (Each Score X it’s probability) 2. I. ( 0 x.24) + (1 x . 20) + (2 x . 32) + (3 X .24) = 
2.57

2.57)2 * .32} + {(3 – 2.57)2 * .24} = 2.25  
II.     2.25 = 1.5 Here is another example of these formulas Group 1: IQ score among students in a class IQ Score # of Students P 100 10 10/23 = .434 115 5 5/23 = .22 125 3 3/23 = . 130 90 4 4/23 = .173 85 1 1/23 = .043 2. The formulas for the table above (pg. 2) a. Expected value i. (100 x .434) + (115 x .22) + (125 x .130) + (90 x .173) + 
(85 x .043) = 104.18
b. RISK formula i. {(100 – 104.18) 2  x .434)} + {(115 – 104.18) 2  x .22)} +  {(125 – 104.18) 2  x .130)} +{(90 – 104.18) 2  x .173)} + {(85 – 104.18) 2  x .043)} = 11.97 or 12 1. STEP by STEP instructions I. Subtract expected value from each score 100-
