Understanding data profession better with distinctions between data analysts and data scientists

According to the World Economic Forum Future of Jobs Report 2023, data analysts, data scientists, AI and machine learning specialists, and digital transformation specialists are among the most sought-after and well-compensated professionals in today's job market. However, while there is a growing interest in data-related career, distinguishing between the roles of data analysts and data scientists may not always be clear. Let us delve deeper into understanding the nuances between these two professions.

Data analysts and data scientists both work with data, but their approaches and responsibilities differ significantly.

Data analysts: Data analysts primarily focus on structured data to address concrete business challenges. Their tasks typically involve: collaborating with organisational leaders to identify data needs, gathering, cleaning, and organising data for analysis, utilising tools like SQL, R, or Python for statistical analysis, identifying trends and patterns in data to provide actionable insights, presenting findings in an accessible manner to guide decision-making.

Data scientists: On the other hand, data scientists leverage advanced techniques to make predictions and derive insights from both structured and unstructured data. Their responsibilities may include: Processing raw data and designing predictive models, developing machine learning algorithms to analyse large datasets, creating tools and processes to ensure data accuracy and reliability, building visualisation tools and dashboards to communicate insights effectively, automating data collection and processing through programming.

While both roles require a strong foundation in data analysis, the educational pathways differ. To be data analysts, one typically requires a bachelor's degree in mathematics, statistics, computer science, or finance. To be data scientists, you need to be prepared for advanced roles in an organisation that often require a master's or doctoral degree in data science, information technology, mathematics, or statistics with sufficient skills in programming.

While a data analyst makes sense out of existing data through routine analysis, writing reports and visualising data, while a data scientist works on new ways to capture, store, manipulate and analyse that data. Oftentimes, a data analyst works toward answering business-related questions whereas a data scientist works to develop new ways to ask and answer those questions.

Data analysts and data scientists both play critical roles in extracting insights and driving decision-making through data. There is often an overlap between their roles too. Data scientists commonly possess a background in data analysis. This familiarity enables them to comprehend the methodologies employed by analysts and develop solutions that yield relevant insights.

Regardless of the chosen path, it is important to note that both professions typically demand a bachelor's or master's degree in a quantitative field such as mathematics, computer science, statistics, or information technology. Pursuing traditional education or alternative pathways like professional certificates from Google or IBM's courses on MOOC platforms, acquiring the necessary skills and real world's project experience is essential for success in these high-demand professions.
