STA 215 Chapter Notes - Chapter 9: Random Variable, Randomness, Dependent And Independent Variables
Document Summary
Random variable- an outcome is random if we know the possible values it can have, but uncertain to which particular value it takes: ex) dice. How many boxes can you expect to open before you obtain all. Trial- each time we obtain a simulated answer to our question; the sequence of several components representing events that we are pretending will take place. Component- uses equally likely random digits to model simple random occurrences whose outcomes may not be equally likely; (opening one box) Response variable- values of the response variable record the results of each trial with respect to what we were interested in; the trial"s outcome; (the number of components/boxes) 1: explain how you will model the component"s outcome. (assign equally likely random. Identify the component to be repeated. (opening of a box) digits)
