1.Comparison
distribution
Compare distributions of your response times under different conditions.
How to use: Check out the check boxes to determine
what kind of data(small, medium, large, and Xlarge) you want to chose.
Click the "begin" button to begin,and you will various boxes appear.Click
the boxes,and then click the "begin" button in turn.Continue the process
until you get all the data. Press "reset" button to restart the experiment.The
data and some basic statistis of the data will show in the textarea.
Highlight and copy the data into a file for further analysis.
2 Confidence
Interval&&Random generator
Let you generate CI for mean from uniform and normal distribution of
various data size. Observe how the actual coverage differs from the nominal
level. The coverage is close to nominal level for data generated from normal distribution.
For data generated from uniform distribution, the coverage is smaller than the nominal level
when the sample size is small since the normal approximation is not good.
However,the coverage is pretty good when the sample size is large enough.

Data Exploration
Let you see graphically how the summary statistics change interactively as you add extra data points.
