About analysis
We use the latest analytical methods and tools to provide audit insights based on evidence and to enhance the scrutiny of public spending.
Our expertise includes:
- data analytics;
- economic and financial analysis;
- qualitative and survey research methods;
- GIS mapping and spatial analysis;
- statistics; and
- modelling.
From embedding data analytics techniques in financial audits to reviewing government’s models, we use analysis to provide assurance on the accuracy of government’s accounts.
We interrogate data for a clearer understanding of issues, providing Parliament and the bodies we audit with deeper insight. Our engaging interactive data visualisations help make our audit findings accessible to a wider audience.
Our specialised knowledge is also used to produce cross-cutting assessments on the value for money of government’s own use of analytical techniques.
The content on this page shows how we use advanced analysis techniques, illustrating what is possible when working with government data.
