The term data scientist is commonly used as synonymous with the term data analyst, even though data scientist is often the last step on the analyst career ladder. The main differences between these two career paths include the scope of responsibilities and the level of proficiency in technical skills.
The data analyst is usually responsible for managing queries and analyzing data within a given department and team. They present their conclusions using charts, graphs, tables, and diagrams.
The data scientist deals with data in a more scientific way. Their skills include advanced mathematical competencies, programming of analytical models, and conducting experiments. The main tasks of data scientists include activities like creating algorithms for data testing, building analytical models, or developing processes for collecting data.
In short, to become a data scientist, you need to have highly developed skills, which are usually acquired while working and gathering experience as a data analyst.
How to become a data analyst?
To start a career as a data analyst, you need to combine analytical skill set, education, and practical experience. Developed mathematical skills and the ability to think logically are crucial for analysts. Technical knowledge of foreign languages (e.g., German, Spanish) is also important because analysts often work in an international environment.
Data analysts have several career paths, and people working in different industries can qualify for them. People planning to make a career in data analytics should develop soft skills and technical competencies to meet the job market requirements.
Key technical skills
Data analysts need to have advanced technical skills to effectively perform their responsibilities. Crucial programming languages include Python and SQL, typically required in job offers for analysts.
Knowledge of database management systems such as MySQL and PostgreSQL is also crucial for a data analyst’s work, as it allows them to effectively manage data. In addition, the ability to work with relational databases is necessary for querying and managing relationships between data sets.
With the help of advanced data visualization software, such as Tableau and Power BI, analysts can transform complex data into clear visualizations that facilitate decision-making.
Practical soft skills
Besides technical competencies, data analysts also need soft skills. The ability to communicate is crucial because analysts must communicate the findings of their analysis to other teams. Analysts should have characteristics such as inquisitiveness and a desire to experiment with different analytical models.
The ability to draw conclusions, teamwork, and time management are essential for successful analysis and data interpretation. Cooperation with different stakeholders and project management are some of the daily challenges that require developed interpersonal competencies. They help not only with a better understanding of business needs but also more effective implementation of strategies.
