Computer Models & Simulations

Standard and Higher Level

A computer model is a representation of a system or process created on a computer, to assist with calculations and predictions. A computer simulation is the execution of that computer model with data over a period of time to generate results data.

The complexity of computer models can vary from small, such as a few calculations in a spreadsheet for personal finances, to massive amounts of numbers and complicated calculations such as studying the potential effect of climate change over the next 1000 years.

Computer models rely on variables and processes to create predictions that can help people make decisions in the real world. Given that people may use computer models to make important decisions, it is imperative to know exactly how accurate a model is.
