Box Plots and Data Spread
by Anonymous
See how one distant point pulls the mean, then use quartiles to make a box plot and spot outliers.

About this app
An interactive statistics learning app for exploring center and spread with a set of nine movable data points. Adjust individual values to compare the mean and median, build a box plot with Q1, Q3, and IQR, and examine standard deviation, distance from the mean, and outliers beyond 1.5×IQR. Guided missions challenge learners to create specific statistical relationships, such as matching the mean and median or widening the interquartile range.
Use cases
- High school students learning descriptive statistics
- Teachers demonstrating mean, median, quartiles, and outliers
- Classroom practice with box plots and data spread
- Self-study of standard deviation and resistance to extreme values
Features
- Move nine data points left or right with step controls
- Compare mean and median through an interactive balance visualization
- Generate a box plot showing Q1, median, Q3, and the middle half of the data
- Display IQR, standard deviation, and each point’s distance from the mean
- Identify outliers using the 1.5×IQR rule
- Complete guided missions across center, box plot, and spread tabs
