I don’t think the weight of a person might have a true 0, the weight of a person from birth to death will never be 0, so I think it should be interval.
What is meant is ‘weight’ as a variable, not ‘weight of a person’. Sorry about that.
As you know the weight of nothingenss is 0, so weight can be 0.
Weight of a person, should have the same properties as weight, right?
The fact that it is not achievable does not mean it is not a true zero. Unlike the temperature example where 0 degrees Celsius is a deceiving 0.
