About this app
An interactive middle-school statistics practice app for building frequency distribution tables and reading histograms. Adjust class frequencies to explore totals, relative frequencies, empty and equal classes, then switch histogram scales and shapes. A challenge section reinforces relative frequency as frequency divided by the total through four guided questions.
Use cases
- Middle-school students learning basic statistics
- Teachers demonstrating frequency tables and histograms
- Independent practice with relative frequency
- Classroom warm-ups or review activities
Features
- Editable frequencies for five classes with total and relative-frequency updates
- Missions for totals, half-sized relative frequency, empty classes, and equal frequencies
- Histogram view with frequency or relative-frequency scale
- Preset distribution shapes: even, rising to the right, and concentrated in one class
- Four relative-frequency calculation questions with answer checking and streak tracking
