About this guide
This guide sets out examples of the principles in the Code of Practice that producers need to adhere to in order to remain code compliant when making changes to statistical methods. It also includes examples of the kinds of materials that can be used to help document this adherence. An important decision will be on the scale and nature of the changes that are being considered and to be proportionate in applying these principles – you need to determine the materiality of the change. Identify if there are fundamental changes to the methods that could affect the statistics – these will need to be understood and explained to users.
