types of models
iconic
analogue
symbolic
8
iconic model

• looks like what it represents
• specific relationship to what it represents
• e.g. scale down or up
• can never share all properties

analogue model

• iconic model not convenient
• properties of a different kind
• economy - bath

analogue model

symbolic model

• abstract
• uses symbols
• words, numbers, variables, graphical
• can handle large complex
• descriptions

model building

• model must represent all variables
• if something missing - distortion
• all variables must be relevant
• not just because data available
• be aware of distortions
• use of different materials
• be careful of data entered
• G I GO
