Resources for GCSE Computing course for the Data Representation topic. The Resource explains how different data is stored, so introducing data types and variables and shows how important it is to make sure the correct variables are selected by the programmer. Uses examples in Python and an excel program ( input form and vba coding) has been created for students to investigate for themselves, what can go if wrong data types for variables are chosen by the programmer. Overflow error, type Mismatch, rounding up errors, Validation etc.
