Applet Collections Description
Rossman/Chance Applets The Rossman/Chance applet collection is focused on statistical topics including data analysis, probability, inference, and mulitple variables. Some applets require java, javascript, or flash.
Physics Applets This applet collection features physics content that starts with basic kinematics and goes to topics such as quantum or nuclear physics. Applets are sorted by the unit with each unit containing at least three applets.
Calculus Applets This applet collection is focused on AP Calculus AB content and features limits, applications of derivatives, integrals, area, etc. It is created using GeoGebra which allows for easy manipulation.
Larry Green's Applets Larry's applet collection is large and covers topics in basic math as well as statistics. Applets are sorted by category and then individual units within each category for easy finding.
Statistics Applets This applet collection features 11 applets covering sampling and sampling distributions. These applets are taken from many different applet collections and put together so the user can easily find applets on this topic.


Applet Description
Central Limit Theorem This applet focuses on the CLT and how normal distributions are made from samples. The user picks an initial distribution to start with as well as a sample size. The applet will take thousands of samples of size n and compute the means. It displays the original distribution followed by the now normal distribution of the means.
Plinko This applet allows the user to play a game of plinko where they drop balls and see what bin they land in at the bottom. They can choose to drop 1, 10, or 100 balls at a time. Once the sample is large enough users will see that the distribution of balls is approximately normal.
Pascal's Triangle This applet displays Pascal's triangle and is interactive. You can change how many rows of the triangle there is as well as highlight multiples of any specified value of n.
Coin Toss This applet focuses on both basic probability rules as well as sampling from a population. Users flip 15 coins at a time and the number of heads and tails are recorded. There's a graphic that shows the number of tosses against the proportion of heads. As you flip more and more you will see the proportion even out to 50%.
Random Walk This applet takes the user through an activity using the Random Walk program. This activity uses probability and compares graphics of coin flipping, a random walk, and Pascal's triangle to see similarities and differences.


Title Type Description
The Galton Board Video This video explains what the Galton Board is and how it relates to Pascal's triangle. It shows how probabilities are calculated to create the approximate normal curve that is found when using the Galton Board.
The Real Pascal's Triangle Meme This meme highlights the relationship between combinations and the numbers making up Pascal's triangle. The last tier also introduces students to Pascal and what he looks like!
So, You Want to Win Plinko? Paper This journal article introduces the reader to the game of Plinko as seen on The Price is Right. It goes through the purpose of the game as well as the end goal for the player. It launches into background mathematics including probability and Pascal's triangle. There are two research questions analyzed that dive into expected value and different distributions.
How Plinko Probabilities & Odds Are Determined Article This article compares playing Plinko to flipping a coin. It shows how the probability for the end bucket changes depending on the path of the puck. After discussing Pascal's triangle it shows that the distribution of pucks if played repeatedly will form an approximately normal distribution which can help you determine where your puck will land.
Pascal's Triangle Article This website goes over the basics of what Pascal's triangle is. It discusses its construction, formula, the binomial expansion, probability, and special patterns.
