Building a business report can be exciting and scary, and it is crucial to ensure solid analysis to avoid misunderstandings.
One of the most common mistakes in data analysis is not knowing the question you are answering, which can lead to producing the wrong answer.
To avoid this mistake, it is important to ask relevant questions before conducting the analysis, such as what decision the report will support and which metric matters the most.
Another common mistake is using incorrect data sources, like pulling data from a test table instead of the production one, which can result in inaccurate conclusions.
