Difference deductive and inductive reasoning
Deductive reasoning: top-down
inductive reasoning: bottum-up
Inductive reasoning
if the premise is true, they support the conclusion but do not garantee its truth
Deductive reasoning
If the premise is true, the conclusion must be true as well
Example of deductive reasoning
- all swans are birds
- all birds are animals
- therfore, all swans are animals

laws describe the necessary relationship between entities, properties, events
what is regularity view of law?
laws of nature simply describe what happens to be the case

practical problems: questions about uniformity of data, repressentiveness of data rights for generalization
