Votes:0 Bayes' Theorem: Conditional Probabilities If you have been to this page before and wish to skip the preliminaries, click here to go directly to the computational portion of the page. For the application of Bayes' theorem to the situation where "probability" is defined as an index of subjective confidence, see the page Bayes' Theorem: "Adjustment of Subjective Confidence" . Bayes' theorem describes the relationships that exist within an array of simple and conditional probabilities. For example: Suppose there is a certain disease randomly found in one- half of one percent (.005) of the general population. A certain clinical blood test is 99 percent (.99) effective in detecting the presence of this disease; that is, it will yield an accurate positive result in 99 percent of the cases where t Read More Go to Site
Votes:0 Let's Do Math! Maria and Cassie were playing a game, and Cassie needed to roll exactly a five to win. Cassie said, "Maria, do you think I should roll both dice or just one? Would I have a better chance of winning if I just rolled one? Maria answered, "I think we can figure it out with math."

The mean, x bar , of the scores is (I can't do an overscore here so imagine an x with a bar over it!) x bar = (x 1 + x 2 + . . . + x n ) / n . This is the average value of the n scores. Another thing to know is how spread out the scores are. This involves the variance x var , the average squared distance from the mean: x var = [ (x Read More Go to Site
