In the first
demonstration, you will examine a simple random walk. Hit the
setup button to place the turtle at the center of the screen, and then
hit go as often as you like to see how the turtle moves.
random walk 1.1.nlogo
In this
demonstration, you can see how far the turtle is from the origin (0, 0).
Run the model several times and graph the distance
how-far?
vs. # of trials.
random walk 1.2.nlogo
In this model, you
can change the number of steps
#steps
and observe how the random walk behaves when you run more and more
trials.
random walk 1.3.nlogo
Now you get to
randomize how long one-step? each step can be. How does that
affect the random walk?
random walk 1.4.nlogo
Here you can change
everything. Try different angles (like 1º or 15º or 45º).
How does the random walk change now? Modify the length of each
step and the number of steps as well. Now that’s a random walk!
MonteCarloPi.nlogo
This final example is
a program by Helene Dauerty (see Intro to Stats and Monte Carlo
tutorials) that shows how to use a random walk to actually calculate π.
Have fun!
