| APPLET | SOURCE | DESCRIPTION |
|
| Comparing Distributions | Rice Virtual Lab in Statistics (Lane) | Two distributions are created from the response times it takes the user to click on squares appearing on the screen, shows histograms and descriptive statistics for both distributions. more
  |
| Interactive Histogram | Virtual Laboratories in Probability and Statistics (Siegrist, Duehring) | Click on graph to add data to a frequency distribution, histogram is constructed and descriptive statistics are calculated, class width can be varied. NOTE: xhtml files may not run in all browsers. more |
| Find the Means of Histograms | Kerbaugh, Fayettesville State Univ. | Create a histogram by entering observations one by one as applet shows how each is incorporated into the histogram, shows the histogram "tilting" to one side with a marker for the mean that the user can slide to balance the histogram and find true mean, user can also move points to see the effect on the mean. more |
| Dot Plot Summaries | Rossman Chance Applet Collection | Generate random data sets of different shapes or with outliers and guess mean, median, deviation, IQR, then check your answers. Includes questions to guide inquiry. more |
| One Variable Statistical Calculator | W.H. Freeman & Co. | Calculate descriptive statistics and generate histograms and stemplots for several example datasets, of special interest are two datasets with the same mean and standard deviation but very different distributions. more
|
| Mean and Median | Rice Virtual Lab in Statistics (Lane) | User observes mean, median, standard deviation and skew of a dataset as they manipulate a histogram, also has discussion of central tendency, skew, center of gravity, prediction as well as exercises. more
|
| Mean Influence | Seeing Statistics (McClelland) | Shows the effects of a single point on the mean. more |
| Median Influence | Seeing Statistics (McClelland) | Shows the effects of a single point on the median. more |
