Use the Simulation tool to model probabilistic situations and analyze the results in tables, graphs, or data sheets.
Create simulations that model simple situations such as flipping a coin, rolling a die, drawing a card, or generating a random integer. Summarize the results in table form or in histograms. Additionally, view basic statistics or analyze the results in Data Analysis.
Build a Simulation
Use the Options menu or toolbar icons to create events and customize simulations with computations. Choose to build a Simple/Common Event or Distribution Event, create a Custom Event, relate events by Computations, model Meta Events, and view a Sample Simulation.
|Pick a card from 52-card deck||Roll a 10-sided die|
|Flip a 2-sided coin||Roll a 20-sided die|
|Roll a 4-sided die||Generate a random digit|
|Roll a 6-sided die||Generate a random integer from a to b.|
|Roll an 8-sided die|
Example 1. Choose then then . Click on and hold down shift to select , then choose Build | (Computations) Add. A new event will be created that will read + (8-sided Die + 4-sided Die). The outcome for this combined event will add the value of the 8-sided Die to the value of the 4-sided Die for each run of the simulation.
Example 2. Choose three times. Hold down the Shift key as you click on each of the digit icons () within the model window. With this selection highlighted, choose Build | Additional Computations | Function. A separate Function Editor window will open describing how each of the selected events are coded (e.g., a:Digit, b:Digit, c:Digit). To relate these events by a function that computes their mean, type (a+b+c)/3 and press Enter (or type average(a,b,c)). A new event that relates the three random digits is listed in the simulation model. Expand or collapse the view (click on the small triangle to the left of the function) to determine which results are displayed in the table and graph.
Note: Only one Meta Event may be chosen at a time.
Example. Choose , then Build | (Meta Events) Count Till See. Double-click on the outcome that you are waiting for (this is simulating a waiting-time situation). If you would like to wait for multiple outcomes from one simulation, hold down the Command key and select multiple outcomes.
Note: When an option from the Sample Simulations menu is chosen it will replace any current simulations. Open a new Simulation window to model multiple situations as separate simulations.
Run a Simulation
After setting up a simulation, use the Simulation menu or their corresponding toolbar buttons to run it.
Note: If the speed is set at a Step pace, click the Go button for each new run.
Note: To clear the build of the simulation choose the button or choose Tool | New.
Note: The Conduct button does not have an effect on the controls that start, stop, and determine the speed of the runs.
View & Analyze Results
Once your simulation has finished running view or analyze the results.
Viewing Styles and Options
Select (or deselect) entries of the View menu to customize what and how the results of a simulation are shown.
Note: A simulation must be built prior to running it (and both must be done before results will be recorded in the table or graph).
Note: Be sure Graph is selected (checked) within the View menu for these settings to be applied.
Save and Record Simulations
The Tool menu provides options for creating new simulations (), opening saved simulations (), printing (), and saving ().
