public class CoinTossLawOfLargeNumbersExperiment
extends Experiment
implements java.io.Serializable

This experiment consists of tossing n coins, each with probability of heads p. The Proportion of Heads (P) and the differences of Heads and Tails (D) are recorded on each update. The discrete probability density function is shown in blue in the distribution graph and are recorded in the distribution table. On each update, the empirical probability density function and moments of the selected variable are shown in red in the distribution graph and are recorded in the distribution table. The parameters n and p can be varied with scroll bars.

Constructor Detail

CoinTossLawOfLargeNumbersExperiment

public CoinTossLawOfLargeNumbersExperiment()
Method Detail

init

public void init()
This method initializes the experiment, including the coin box, the toolbar with the random variable choice, and the random variable table and graph.

Overrides:
init in class Experiment

public java.lang.String getAppletInfo()
This method gives basic information about the applet, including copyright information, descriptive information, and instructions.

Specified by:
getAppletInfo in interface IExperiment
Overrides:
getAppletInfo in class Experiment
Returns:

doExperiment

public void doExperiment()
This method defines the experiment. The coins are tossed and the number of heads and proportion of heads are computed.

Specified by:
doExperiment in interface IExperiment
Overrides:
doExperiment in class Experiment

public void step()
This method starts the step process.

Specified by:
step in interface IExperiment
Overrides:
step in class Experiment

run

Overrides:
run in class Experiment

stop

public void stop()
This method stops the step process, if necessary, and then calls the usual stop method.
