#2001
Central Limit
Theorem

click here for more information

The program CenLimit shows the effects of the central limit theorem. The user may select various distributions drawing different numbers of samples to calculate the means. The distribution of the means is plotted..... more

Leverage
Effect in
Regression

click here for more information

This program visualizes the effects of outliers to regression lines. The user may pick up a point with the mouse and move it across the chart. The resulting regression line is automatically adjusted after each movement, showing the effect in an immediate and impressive way..... more

Error Surface
of Linear
Regression

click here for more information

Linear regression can be seen as an optimization problem, searching for the lowest point of the error surface. This program allows to play with the error surface of a regression line and to find the optimum fit by intuitive means...... more

Distribution
of the
Correlation
Coefficient

click here for more information

The correlation coefficient is one of the commonly used statistical measures. Despite its frequent use, the fact that the correlation coefficient shows a broad distribution if too few observations are used is not well-known....... more

Regression
of Weakly
Correlated
Data

click here for more information

There is a common mistake about the linear regression of x-y-measurements with small or no correlation between them. This simulation tries to shed some light on this aspect of linear regression....... more

Time Averaging
of Signals

click here for more information

Signals below the detection limit cannot be measured without improving the signal-to-noise ratio. This program shows the improvement of the SNR by accumulating signals....... more

Measures of
Location

click here for more information

This program shows the effects of individual data points on some univariate measures of location (mode, median, mean, and trimmed mean). The user may pick and move individual data points, watching the change of these measures...... more
