Description
Who it’s for: Owners, managers, buyers and anyone who works with business numbers who want the whole picture of averages and spread, not one number at a time.
What’s in the box: season 4 of the Numbers for Business series, five courses in order.
- Mean: Ten till slips, one fair figure.
- Median: Two early bookings hid a gap.
- Mode: One shelf card: which bundle?
- Standard deviation: Same mean, very different service.
- Coefficient of variation: Bigger swings, or just bigger?
How it works: each course is a micro course of about 30 minutes with its own film, lesson, decision, practice tools and boardroom. Finish all five for the season certificate.
