Binomial Distribution & Expected Value
by Anonymous
Move the probability bars to see expected value as the balance point, then change n and p to reshape the binomial distribution.

About this app
An interactive learning app for exploring the binomial distribution, expected value, and standard deviation. Adjust probability weights to balance a seesaw at E(X), then change the number of trials n and success probability p to see how the binomial bars shift, become symmetric, or spread out. Guided missions provide practice with expectation, variance, the mode, and the relationship between binomial and normal distributions.
Use cases
- High school students studying probability and statistics
- Teachers demonstrating expected value with a visual model
- Learners exploring how n and p change a binomial distribution
- Practice with binomial mean, variance, and standard deviation
Features
- Interactive seesaw showing expected value as the balance point
- Adjustable probability weights for five possible values
- Binomial distribution chart controlled by n and p
- Standard deviation view with mean, Β±1Ο range, and normal approximation
- Guided missions with reset and next-step controls
