What is the difference between changing the “data” and changing the “rules” within the model?
Changing data is changing the values/variables within a cell, changing the rules is editting/changing the formulae in cells. Candidates are also expected to write about how they have used a spreadsheet, describe how they changed the variables in the spreadsheet and what effect this had on other variables to meet this criterion: “Write about how they have used the different options available within the model”.
