 Program Short Description Reference #2001Central Limit Theorem 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 Teach/Me Data Analysis #2002Distribution Calculator Lines The program DistCalc calculates probabilities and critical values for the most important distributions. The purpose of this program is to show the concept of critical values and the replacement of printed distribution tables......more Teach/Me Data Analysis #2003LeverageEffect inRegression 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 Teach/Me Data Analysis #2004Error Surfaceof LinearRegression 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 Teach/Me Data Analysis #2005Distributionof theCorrelationCoefficient 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 Teach/Me Data Analysis #2006Regressionof WeaklyCorrelatedData 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 Fundamentals of Statistics #2007Time Averagingof Signals 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 Teach/Me Instrumentelle Analytik #2008DiscreteDistributions Discrete distributions are an important class of distributions when it comes to sampling binary data. This program calculates the binomial, the hypergeometric and the Poisson distribution. ....... more Fundamentalsof Statistics #2009Linear Regressionfor ChemicalAnalysis Linear regression is a commonly used method to establish a relationship between a measured variable and a response variable. This program allows to calibrate this relationship..... more unpublished #2010Measures of Location 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 Fundamentalsof Statistics #2011CauchyDistribution This program simulates a Cauchy random process and allows to calculate the mean as a function of the sample size ........ more Fundamentalsof Statistics
