Resolved: Can ratio data have decimal numbers or it should be integer???

For Question 2 , I believe there is no weight that is zero, something can have o.000000001 weight which does not make it zero hence with the answer of question 2 why is it ratio rather than interval. since intervals have no true zero and also weight is continuous but not discrete.

Weight is a ratio variable, not an interval variable, because it has a defined zero point and the ratio of two weights has a meaningful interpretation1. For example, a weight of 4 grams is twice as heavy as a weight of 2 grams
