| APPLET | SOURCE | DESCRIPTION |
|
| Marbles | Interactivate | User can draw a specified number of colored marbles, with or without replacement, from a pool of marbles specified by user. Can run multiple trials to observe relative frequencies and compare to theoretical. more |
| Adjustable Spinner | Illuminations Resources for Teaching Math | Can select number of sectors on a spinner (up to 12), adjust area of each, generate a number of spins and compare to theoretical distribution. Use for classroom simulations. more |
| Simulating the Stock Market | Prentice-Hall applets (West) | Users simulate whether the stock market increases or decreases over multiple days and compare actual proportion of increasing days to theoretical to see that actual proportion approaches theoretical as number of days increases. more |
| Probability | WolframAlpha.com | Can type in expressions such as "32 Coin Tosses" or "5 dice" and get outputs such as probability of given events, graphical displays of outcomes, expected value, standard deviation, also computes probabilities of cards and lotteries. more |
| Spinner Experiement | Siegrist and Duehring, accessed through SOCR (Statistics Online Computational Resource) | Can select the number of sectors on a spinner (up to 200), adjust area of each if desired, output results of individual spins as well as the distribution, both observed and theoretical. Use for classroom simulations. more |
| The Ball and Urn Experiment | Siegrist and Duehring, Virtual Laboratories in Probability and Statistics | Users can simulate choosing a specified number of balls (with or without replacement) from urns containing a specified number of balls total and red balls, counting the number of red balls in each sample, and comparing observed to theoretical frequencies. more |
| Probability Applet (Probability Aquarium) | Schneiter, Utah State Univ. | Sequence of exercises of increasing difficulty in calculating probabilities of choosing certain types of fish out of an aquarium with or without replacement, option to show answers and solutions. more |
