Method Detail

init

public void init()

Initialize the experiment: tables, graphs, scrollbars, labels, drop-down box

Overrides:

init in class Experiment

setNormalAsDefaultDistribution

public void setNormalAsDefaultDistribution()

This method sets the default distribution

constructSamplingDistributionObject

public void constructSamplingDistributionObject()

This method constructs an instance of the SamplingExperimentMainFrame object that is used to to the simulation, rendering and result computing

constructDistributionPanelObject

public void constructDistributionPanelObject()

This method constructs an instance of the SOCRDistributions object, a subclass of SOCRApplet, that provides access to the fControlPanel distribution selection interface

doExperiment

public void doExperiment()

This method defines the experiment. A random sample of the specified distribution is obtained, the sample statistics are computed and the sampling distribution is displayed.

Specified by:

doExperiment in interface IExperiment

Overrides:

doExperiment in class Experiment

step

public void step()

This method starts the step process.

Specified by:

step in interface IExperiment

Overrides:

step in class Experiment

run

public void run()

This method stops the step process, if necessary, and then calls the usual run method.

Overrides:

run in class Experiment

stop

public void stop()

This method stops the step process, if necessary, and then calls the usual stop method.

Specified by:

stop in interface IExperiment

Overrides:

stop in class Experiment

update

public void update()

This method updates the experiment, by updating the random variable graph.

Specified by:

update in interface IExperiment

Overrides:

update in class Experiment

updateSummaryStatsTables

public void updateSummaryStatsTables()

reset

public void reset()

This method resets the experiment, including the random variable and the random variable graph.

Specified by:

reset in interface IExperiment

Overrides:

reset in class Experiment

resetSample

public void resetSample()

This method resets the random variable and its graph.

stateChanged

public void stateChanged(javax.swing.event.ChangeEvent event)

This method handles the scrollbar event for changing the sample size.

Specified by:

stateChanged in interface javax.swing.event.ChangeListener

Overrides:

stateChanged in class Experiment

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent evt)

Description copied from class: Experiment

This method handles the action events associated with the simulation buttons. The single step button calls the step method, which runs the experiment one time, and then stops. The run button calls the run method, which runs the experiment repeatedly. The stop button calls the stop method, which stops the run mode and then calls the update method if necessary. The reset button callse the reset method. The about button shows a message dialog box with the text from getAppletInfo method. This method also handles the timer events.

Specified by:

actionPerformed in interface java.awt.event.ActionListener

Overrides:

actionPerformed in class Experiment

Parameters:

evt - the action event

getFreqSOCRDistributionData

This method adds a new component to the second toolbar.

Overrides:

addTool in class Experiment

Parameters:

c - the tool

getAppletInfo

public java.lang.String getAppletInfo()

Description copied from class: Experiment

This method returns basic copyright, author, and other metadata information.

Specified by:

getAppletInfo in interface IExperiment

Overrides:

getAppletInfo in class Experiment

Returns:

applet information

getOnlineDescription

public java.lang.String getOnlineDescription()

Specified by:
