Jun 2, 2021 4:02:15 PM

The world now is more data-driven than ever. Historical data is conspicuously the trigger for data-driven decisions; banners, advertisements, emails, and spam are all the results of data analysis. The data explosion has created the demand for analysts and scientists and thus, calls for the need to understand the difference between the roles.

The following key points are the differences between the roles of a data analyst and data scientist.

Comparisons 

Data Analyst

Data Scientist

Definition

  • Deals with exploratory analysis, identification of trends and patterns, and the creation of visualizations that interpret data so that business leaders can make data-driven strategic decisions.

  • Deals with the design, construction, and implementation of data modeling using algorithms and predictive models.

Roles and Responsibilities

  • Captures insights to solve problems such as sales forecasting in a given region, the effect of marketing campaigns on revenue, and more.

  • Asks questions about defining and improving the quality of data by using data analysis algorithms (machine learning) to understand the information gathered.

Skills Required

  • Tackles responsibilities such as DB administration and maintenance along with reporting and statistical tools. Specialization tools may include but are not restricted to, R, SAS, SQL, and SPSS.

  • Must have skills in data design/modeling, coding, problem-solving with software development using Python, Java, and Big Data.

Expectations

  • The analyst in most cases is not involved in data extraction, but they use them to create insights for an organization to formulate its strategy to reach its objectives.

  • Focuses on developing, cleaning, and organizing datasets by asking the right questions about the sources of data, and establishing a pipeline for data acquisition.

  • Leverage algorithms (machine learning) and statistical models to gather and shape accumulated data that can be easily understood. 

  • Followed by the repeated deployment of experiments, fine-tuning them, and measurement metrics to achieve better results.
