Taking the testPreservation coefficient
Notes
We define a grid of consumer behaviour, from the frequent new buyer to the person who makes a major effort to keep their furniture as long as possible. We assume that people who say they often buy new keep their furniture for half of its average lifespan, while those who keep their furniture postpone its average lifespan. This grid may evolve if new sources or studies are added to it.
How is this figure calculated?
- Formule:
- Variations:
- Divers . ameublement . préservation = 'faible'
- 1 / 2
- Divers . ameublement . préservation = 'maximum'
- 4 / 3
- 1
