Lesson Summary
You will learn to use a simple model to predict the weather.
Key Notes

3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
A probability model can be used to predict the weather. Some models are better than others at predicting the weather.
2. Use this key word in a maths sentence and explain it clearly. 'Forecast'
A forecast is a prediction of a future event occurring (based on data). Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: If the weather report has the rain icon, it means it will rain. Correction: The rain symbol is to denote what type of rain it is likely to be should it rain. The percentage chance of rain then informs us about how likely it is to rain.
