s= |
sample SD, estimate of o |
Newton's Rules: |
1) parsimony- natural events should be explained in simplest way
2) natural order: assign same causes to same effect
3) what we learn from experiments can be applied to similar structures outside of experimental reach
4) theories obtained should be considered true until new evidence proves them incorrect |
Deduction |
movement from general theory to particular statements concerning data |
Induction |
movement from data set to general theory/concept |
