What Does A Data Analyst Do
Data analysts are responsible for answering questions about data. Unlike data scientists, data analysts are not concerned with using data to find trends or figuring out the businesss future. Their job is to analyze historical data, create and run A/B tests in product, and even design systems. Data analysts need to be proficient at data storing, warehousing, and utilizing tools such as Tableau.
Core Data Analyst Skills
- A/B testing: A/B testing is a statistical approach used to compare two versions of a variable in a controlled environment. A/B testing is employed to determine which variable version performs better.
- Domain knowledge: you can think of domain knowledge as specialization. For example, if you have significant experience working specifically in the retail sector, you have domain knowledge in retail.
- Excel: Microsoft Excel is often used to manage small data sets.
- Data Visualization: like data scientists, data analysts must know how to use data visualization tools such as Tableau to tell stories to stakeholders with data.
- Programming: data analysts should have competent programming skills in languages like R and Python.
- SQL: SQL is a database language used for data management and building database structures. SQL is often used instead of Excel because its more apt at handling large datasets.
- Reporting: as a data analyst, you need to report your data insights, which means you should also have excellent communication and presentation skills.
Are You A Data Scientist
Data scientists love complexity. They enjoy answering questions that are broad and amorphous. They thrive on project-based assignments, and get excited about delivering insights. Data scientists are less likely to work on a wide variety of assignments in comparison to data analysts. Therefore, you might be a good fit for a career as a data scientist if:
- You enjoy complexity.
- You like delving into a single question.
- Youre okay with not finding an answer to a problem.
