The role of a Data Analyst in a company is to collect, analyze and interpret large sets of data to identify patterns and trends that can be used to make informed business decisions. They help companies understand their customers, improve their products or services, optimize their operations, and identify new business opportunities.
There are several types of data analysis techniques, including descriptive analysis, inferential analysis, predictive analysis, and prescriptive analysis. Descriptive analysis focuses on summarizing and describing data, while inferential analysis involves making predictions and drawing conclusions based on sample data. Predictive analysis uses statistical models to predict future trends, and prescriptive analysis suggests the best course of action based on the insights gained from data analysis.

While there is some overlap between the roles of a Data Analyst and a Data Scientist, the primary difference is in the level of expertise required. Data Scientists typically have a more advanced degree in a field such as computer science or statistics and are responsible for developing predictive models and designing experiments. Data Analysts, on the other hand, typically have a bachelor’s degree and focus on collecting, analyzing, and interpreting data to inform business decisions.
The typical career path for a Data Analyst may involve starting in an entry-level position, such as a Junior Data Analyst or Data Analyst Intern, and then progressing to a Senior Data Analyst or Managerial role. Some Data Analysts may also choose to specialize in a particular industry or field, such as healthcare or finance, or may pursue further education to advance their skills and career opportunities.
