Data Analysts
Data Analysts are professionals who collect, process, and perform statistical analyses on large datasets to identify trends, patterns, and insights that can inform business decisions. They use various tools and techniques to clean and transform data, and then apply statistical methods to extract meaningful insights from the data. Data Analysts are responsible for creating reports and visualizations that communicate their findings to stakeholders in a clear and concise manner. They work closely with other members of the data team, such as Data Scientists and Data Engineers, to ensure that data is accurate, reliable, and accessible. Data Analysts are also responsible for identifying opportunities for process improvement and making recommendations for changes to data collection and analysis methods.
