The skills a data analyst needs to succeed vary depending on their role and the organization they are working in. Generally speaking, they must have a good understanding of mathematics and statistics, as well as expertise in at least one programming language. Additionally, they must have knowledge of software tools for data extraction, modeling, and analysis. 

Not only must data analysts have technical skills, but also the ability to think critically and logically. They must be able to interpret data and make informed decisions based on that information.
