Bivariate Data

We wish to emphasize that the data sets presented so far are associated with a single random variable. This means that each sample refers to a single, specific population or population characteristic. The technical name for such data is univariate. Data which derives from two separate populations or population characteristics is called bivariate.

Conditional Probability: Part 2

The conditional probability of event B given that event A has occurred, P(B/A), was introduced in Chances Are…?. Here we provide additional examples of conditional probability with a special emphasis on applications of the general multiplication rule P(A and B) = P(A) x P(B/A), An extension of the general multiplication rule {P(A and B) = Read more about Conditional Probability: Part 2[…]
