# Data Analysis Handbook
Focuses on processing and analyzing data, primarily structured data, to extract useful information and support business decision-making.
* It includes tasks such as cleaning, organizing, calculating metrics, statistical analysis, and creating visualizations.
* Its purpose is to answer specific questions and solve specific problems based on existing data.
* It requires skills in statistics, database management, and tools such as Excel, SQL, and visualization tools.
* It is more descriptive and exploratory, focusing on interpreting data to improve efficiency and support business operations.
