Chapter 11-UnderstandingRandomness

1. Random

   • An outcome is random if we know the possible values it can have, but not which particular value it takes.

2. Generating random numbers

   • several Internet sites offer an unlimited supply of equally likely random values.

3. Simulation

   • a real-world situation by using random-digit outcomes to mimic the un- certainty of a response variable of interest

4. Simulation component

   • equally likely random digits to model simple random occurrences whose outcomes may not be equally likely

5. Trial

   • The sequence of several components representing events that we are pretending will take place

6. Response variable

   • Values of the response variable record the results of each trial with respect to what we were interested in
