Agenda
- Number talk: Estimation Duels — what will the period be?
- From your own data to an equation: amplitude, axis, period, phase, in that order
- Test against a point you did NOT use to build the model
- The extrapolation argument: how far ahead would you trust it, and what in the situation sets the limit?
Things to do before our next class
- Equation fitted and tested; one prediction made.
