How do I choose the right method of collecting data?
You must plan the methodology in detail to consider the most effective and accurate way of collecting the data you require. You must decide whether you will look back at existing data (retrospective) or collect data as it happens (prospective). You must also ensure that your sample size is large enough to be representative of the population, condition or process you are auditing.
How do you analyse your audit data?
The purpose of data analysis is to find evidence to answer the questions posed by the audit objectives. There are two main types of data analysis:
Quantitative data: Is concerned with numerical or specific data.
Qualitative data: Is usually descriptive rather than numerical.
