Here is file a remake of the Demo 47 file from Fifty Fathoms. This is the one about the wait-time (geometric) distribution.

This ought to work fine with the demo as written, but as a couple of extra bonuses:

• You can see the source collection (which now has 100 balls) and which ones are red.
• You control the number of red balls with a slider.
• If you change the number of red balls, the measures graph splits so you can see both distributions. (The disadvantage here is that to start fresh, you have to empty the Measures collection. Just select all and Delete Cases or Cut.)

Here is the baby-step lemonade simulation written as a Flex project.

Key Publishes Fifty Fathoms for Version 2!

Key Curriculum Press has taken over Fifty Fathoms and published an edition of the book updated for Fathom version 2. Same great demos, better layout, and three-hole punched!

But you can't buy it here. Click the image to go to Key.

This is a math book that emerged from our science project.

Visit the eeps Data Zoo!

Zoo fans! We now have some new and interesting data (including Astronomy stuff!) from our science project up on the web site. These include slinky data from eeps laboratories, as well as some student work on lenses.

We find and generate a lot of data that may be of interest to anyone who enjoys looking at or teaching about data analysis. We post it on this site for your enjoyment and free use.
