Probability
Random Experiment: A process that results in one of a number of possible outcomes.
The specific outcome that occurs cannot be predicted with certainty.
o Ex: Flipping a coin
o Outcomes: Heads or tails
Exhaustive: list of all possible out
Conditional Probability
Conditional rule: Let A and B be events and Pr cfw_B > 0
Pr(A given B) = Pr(A B)/Pr(B)
Multiplication Rule: Pr(AB)=Pr(B|A)Pr(A)=Pr(A|B)Pr(B)
Now, if the events are independent Prcfw_A B = Prcfw_APrcfw_B, but in this case Prcfw_B|A
Stratified and cluster sampling both attempt to deal with
problems with simple random sampling.
The first problem is that, while a simple random sample may
technically be unbiased, it may not be representative. For
example, suppose my population comprises
