Eye Colours, Shares, Whiskers: Mode, Geometric Mean and Boxplot

Higher Mathematics 2 · Reutlingen University
For categories the mode counts, for growth the geometric mean. The interquartile range measures spread robustly, and the boxplot shows location and spread at a glance.

Eye Colours, Shares, Whiskers: Mode, Geometric Mean and Boxplot
Prof. Dr. Dirk SchiebornHigher Mathematics 2 · Reutlingen UniversityAn explainer film in six chapters, made from a real lecture: why only the mode is left for eye colours, how much production grows per year on average, why you multiply instead of add, what a share with plus 50 and minus 50 per cent, a portfolio and bacteria have in common, why the range depends on the salary of a single manager and the interquartile range does not, and how a boxplot shows location and spread at a glance. Pause anywhere and ask.

- AskTap “Ask” and type what you want to know. The answer comes inside the film, with picture and voice.
- Steer itTell it what to show, for example “Do this with z = 2 − 3i”. The film sets up the app and works it out.
- Try it yourselfWhile it is paused, drag points and sliders yourself. “Continue” takes you back into the film.
Without an account: five questions per visit. With an account you can also ask by voice.
