Data Analyst Job Description

The job of a data analyst is to analyze data and determine data relevance to people. The data derived from different sources tell an analyst about the users’ preferences that generated the data. These patterns and trends also help data analysts to narrow down their target audience. A data analyst’s other responsibilities include collecting data from multiple sources, maintaining databases, ensuring data clarity, and creating graphs.

Relationship between a Data Analyst and Data Scientist

Data analysts and data scientists can be mistaken for each other as they share similarities but are not identical.

On the other hand, a data scientist creates algorithms and statistical models, organizes undefined data sets, etc.

Relationship between a Data Analyst and Business Analyst
