This demonstration, by David M. Lane of Rice University, allows you to view the binomial distribution and the normal approximation to it as a function of the probability of a success on a given trial and the number of...
The applet allows users to sample from a normal distribution or from a uniform distribution. It shows the expected values and the observed values and computes the deviation. Then, a chi-square test shows if the...
Created by David Lane of Rice University, this applet simulates experiments using 2 x 2 contingency tables. You specify the population proportions and the sample size and examine the effects on the probability of...
This applet, by David M. Lane of Rice University, shows how the correlation between two variables is affected by the range of the variable plotted on the X-axis. Exercises and definitions to key terms are given for...
This case study, by David M. Lane of Rice University, assesses the question, "Is it easier to learn to use computer software that uses natural language commands?" Main concepts are analysis of covariance, adjusted means...
