- only work for a restricted range of values
Stages of mathematical model are...

- 2. math model devised
- 3. model used to make prediction
- 4. Experimental data collected
- 5. Compare pridiction and observed outcome
- 6. Stats test to see how well model describe real world
- 7. model can be refined if needed
