... 5) Two events A and B are independent if knowing that one occurs does not change the probability that the other occurs. If A and B are independent, P(A and B) = P(A)P(B) This is the multiplication rule for independent events. Two consecutive coin tosses: P(first Tail and second Tail) = P(first Tail) ...

... Analysis of Variance • Of course there is a sampling distribution of F - if you repeated your experiment many times you would get a distribution of Fs • The shape of that distribution depends on two different degrees of freedom: – MSeffect has k-1 degrees of freedom – MSerror has k(n-1) degrees of ...

... becasue we have assumed a ”fair” die. If we instead assumed the die was weighted so that a 6 showed up half of the time, then the measure would not be uniform. Every set with a 6 would have at least a probability of 12 . So, we can now calculate the probabilities of events. This is nice and useful, ...
