Sample Means and Confidence Intervals
by Anonymous
Draw samples repeatedly to watch the sampling distribution of the mean narrow, and count how often the confidence interval captures the population mean.

About this app
An interactive statistics learning app for exploring sample means and confidence intervals. Draw repeated samples from a population, compare how sample size affects the sample mean, collect hundreds of sample means to see their distribution narrow as the standard error decreases, and generate intervals to observe how often they contain the population mean.
Use cases
- High school students learning probability and statistics
- Teachers demonstrating sampling error and standard error
- Learners comparing small and large sample sizes
- Classroom activities on confidence levels and interval coverage
Features
- Interactive sample drawing with adjustable sample sizes
- Repeated sampling that displays changing sample means
- Collection of 100 or more sample means to visualize their distribution
- Confidence interval experiments with adjustable confidence levels
- Visual distinction between intervals containing and missing the population mean
- Guided missions covering sampling, distributions, and confidence intervals
