In an examination students will not be expected to identify more than four variables in a given system.
Let's answer this question by looking at a few different systems and imagining which variables might be the most impactful.
a sports player[edit]
If I wanted to create a model of a sports player what variables might I choose? I want to choose a variables that are meaningful. Maybe:
- number of injuries
- age
- number of points scored
- number of games won
- number of games lost
I think these variables MIGHT help me model a sports figure.
a country[edit]
Maybe I wanted to create a model of a country. The variables I choose might be related to what I want to do with my model.
- percentage of population with electricity access
- electricity - consumption
- electricity - exports
- electricity - imports
These variable are used from the CIA world factbook with gratitude. I wonder why they create models of EVERY COUNTRY ON EARTH?
a car[edit]
I wonder how these variables might inform my choices about buying a car:
- total cost
- monthly average gasoline cost
- monthly repair cost
- monthly resale value
Standards[edit]
- Identify the variables required to model a given system.
