2 Describing Data- Frequency Tables, Frequency
... A measure of location, such as the mean or the median, only describes the center of the data, but it does not tell us anything about the spread of the data. For example, if your nature guide told you that the river ahead averaged 3 feet in depth, would you want to wade across on foot without add ...

Discrete probability
... P (A), called the probability of A, measures how probable it is that the event A will occur, i.e. that the outcome will be some member of A. The function P must have the following properties. (1) 0 P (A) for all events A, and P (S) = 1. ...
