What is a Data Analyst?

A Data Analyst wears many hats. They are tasked with collecting, cleaning, organizing, and analyzing large sets of data. Data Analysts rely on their technical training when handling data to ensure that it’s high-quality and accurate before performing analyses. Then, they process it, visualize it, and present it so that policymakers can make decisions based on their findings to better optimize performance.

All data analysis begins with a driving question or problem. The Data Analyst's job is to apply their training and expertise to find an answer to this question and share this answer with others at an organization who can use it to drive the decision-making process. The analysis techniques used by Data Analysts often unearth metrics or trends that may not otherwise be apparent when looking at extensive data. A Data Analyst can then use these insights to help the organization improve efficiency and optimize its various processes.

Data Analysts work in many industries, such as government, finance, business, science, healthcare, criminal justice, and academia. Many data analytic techniques are currently automated into mechanical algorithms and processes so that data-driven conclusions can be found more quickly to time-sensitive questions.
