Direction: For each following applet, the
density and moments of the random variable are shown in blue in the
distribution graph and are recorded in the distribution table. On each
update, the empirical density and moments are shown in red in the distribution
graph and are recorded in the distribution table. The parameter can be
varied with a scroll bar.Press "Step" button
to show each simulation.You may see a serial of simulation by choosing
the number of simulation from the "stop freq" list box(the default number
is 10) and pressing "run" button.Renew or stop the process by choosing
"reset" button or "stop" button,respectively.
The
Finite Order Statistic Experiment----The experiment consists of selecting
n balls at random (without replacement) from a population
of N balls, numbered from 1 to N. For i = 1, 2, ..., n, the i'th smallest
number in the sample, X(i) (the i'th order statistic), is recorded on each
update. The distribution and moments of X(k) are shown in the blue
in the distribution graph . When the simulation runs, the empirical distribution
and moments of X(k) are shown in red in the distribution graph.

Statistic Experiment
The Matching Experiment----The matching experiment is to randomly permute n balls, numbered 1 to n. A match occurs whenever the ball number and the position number agree. The matches are shown in red. The number of matches N is recorded on each update.
The
Birthday Experiment----The birthday experiment is to draw a random
sample of size n with replacement from a population of size
N. the indicator variable of the event that there is at least
one duplication in the sample t is denoted I.
