- Develop statements about you think future observations will be.
- Test the prediction and observe what happens.

Can math predict the future?
Scientists, just like anyone else, rarely if ever predict perfectly. No matter what data and mathematical model you have, the future is still uncertain. So, scientists have to allow for error in our fundamental equation. That is, Y = f(X) + E, where “E” encompasses our inability to predict perfectly.
What is the difference between a forecast and a prediction?
Prediction is concerned with estimating the outcomes for unseen data.
