What is the Role of a Data Analyst?

Data Analysts typically work with structured data to tackle specific business issues using a range of tools including visualisation software, statistical analysis, and fundamental programming languages. They gather data to discern trends or track key performance indicators (KPIs) that aid business leaders in understanding and addressing challenges. For instance, a Data Analyst might gather sales data for a business and devise a dashboard that offers insight into areas where sales are increasing or decreasing.

What is the Role of a Data Scientist?

Data Scientists, on the other hand, work with both structured and unstructured data to solve potentially undiscovered problems. They utilize sophisticated analytical methods such as Machine Learning and Statistics to make future predictions, using programming languages like Python or R. A significant portion of their time is spent on data cleaning prior to any exploration. Essentially, a Data Scientist is an advanced version of a Data Analyst. As an example, a Data Scientist might gather sales data and employ time-series forecasting techniques to help companies pre-emptively plan for product demand and location. This can assist companies in optimizing resource distribution in production and logistics. Furthermore, Data Scientists can help enhance marketing strategies by using a consumer segmentation approach to analyze consumer purchase habits, demographics, age, and so forth.

Educational Requirements for Data Analysts and Data Scientists

Data Analysts typically possess a bachelor’s degree in various fields, such as engineering, statistics, economics, or even an MBA. However, Data Scientists usually hold more advanced qualifications like a master’s degree or Ph.D. in areas like computer science, statistics, data science, economics, or related disciplines.

Various studies corroborate this. For instance, an survey in 2017 showed that just 6% of job advertisements for Data Analysts asked for a master’s degree, while research Works indicated that an overwhelming 94% of Data Scientists possess at least a master’s degree.

That being said, possessing a bachelor’s or master’s degree isn’t a strict prerequisite for pursuing a career in either field, as long as you’ve mastered the necessary technical skills to be a Data Scientist or Data Analyst.
