Roles and Responsibilities of a Data Analyst
- Data collection: Surveys, web analytics, and dataset purchases are all ways that analysts get data. However, firms occasionally make data available to analysts, so they don’t always have to get it themselves.
- Data Normalization: Data inaccuracies are located and corrected by analysts, including duplicates. They also spot anomalies and outliers. Additionally, analysts use tools like Microsoft Excel or computer languages. This is used to maintain consistency and preserve the correctness of their interpretations.
- Create Models: Data analysts are frequently in charge of data modeling. These involve deciding how to construct database structures and how to store and compare various categories of data.
- Contextualize: Once the data has been evaluated, analysts will look for links in the larger business environment. These include the general market and industry trends on a local and global scale.
- Interpretation: Data analysts then interpret the trends and patterns they find in the processed data to turn them into insightful knowledge.
- Presentation: Data analysts must use charts, and other tools to present data findings. This helps stakeholders, clients, management, and colleagues.
