Data Analyst vs Data Scientist: Roles, Skills & Pay

TL;DR

• Data analysts focus on cleaning, analysing and visualising data to support business decisions.
• Predictive algorithms, machine learning models and advanced analytics are the focus of data scientists.
• The main distinctions are in duties, level of technical expertise and method of problem-solving.
• Because of their complex roles and specialised skills, data scientists typically earn higher salaries.
• As data-driven decision-making spreads worldwide, both professions offer excellent growth prospects.

Choosing between becoming a data analyst and a data scientist starts with one basic difference. A data analyst is required to focus on analysing existing data to identify patterns, produce reports, and support day-to-day business decisions. On the other hand, a data scientist is in charge of creating predictive models and resolving challenging issues with advanced programming and machine learning methods in addition to a fundamental grasp of statistics.

The roles also differ in skills and pay. Data analysts typically need strong Excel, SQL and data visualisation skills, while data scientists require deeper expertise in Python, statistics and algorithms. As a result, data scientist salaries are usually higher, especially with experience.

What is the Job of a Data Scientist?

Data scientists perform a multifaceted role in companies. They do more than just evaluate facts to anticipate trends. Their job roles include developing data-driven products, building advanced algorithms to address critical issues and utilising more sophisticated statistical methods than data analysts. A data scientist is also responsible to manage and supervise the framework of databases and information storage to ensure easy access and strong security.

The key responsibilities of a data scientist include:

• Building Predictive Models: Data scientists develop models and utilise machine learning to bring automation in the process or anticipate future trends.
• Developing Algorithms: Another core responsibility of a data scientist is to build algorithms that help process and evaluate large volumes of figures efficiently and promptly. 
• Creating Data Visualisation: They also create visual representations, but they do it in a more complex and interactive way. They help stakeholders grasp the results of machine learning models or complex information patterns.
• Developing Product: A data scientist in a reputed company works closely with product teams, designs products, services, or processes and helps organisations meet their goals. 
• Promoting Machine Learning and Artificial Intelligence: With efficiency in AI and machine learning, data scientists utilise these technologies to develop systems that can handle tasks requiring human intelligence.

Data Analyst VS. Data Scientist: Differences

Data analysts and data scientists are two distinct roles within an organisation. Here are the differences:

• A data analyst extracts key information from existing data through analysis and report writing. On the other hand, a data scientist collects facts and figures in new ways and stores, manipulates, and analyses that information.
• A data analyst focuses on addressing business-related issues, while a data scientist develops new methods to address and solve those issues.
• A data analyst relies on database management software, advanced tools and business intelligence programs. On the contrary, a data scientist uses machine learning, AI, Python, and Java to manipulate and assess details.

If you love playing with digits and spending time doing computer programming, being a data analyst or scientist can be your perfect career path. 

Here is a detailed insight and comparison between a data analyst and a data scientist that you can go through to understand their roles and responsibilities:

Data Analyst VS. Data Scientist: Salary Analysis

The salary differences between a data analyst and a data scientist largely depend on factors including skills, key responsibilities, experience level, expertise, complexity of their tasks and geographic location. 

In general, data scientists receive higher remuneration than data analysts due to their higher educational qualifications, sophisticated technical expertise, and the nature of their work. Here's an overview:

Salary of a Data Analyst

India: At the entry-level, data analysts with only 0 to 1 year of experience earn around INR 4 LPA to INR 6 LPA on average. With 2 to 5 years of experience and strong skills in SQL, Excel and data visualisation tools, salaries can grow to INR 8 LPA to INR 10 LPA, especially in IT, consulting and fintech sectors.

Globally: Salaries vary between £25,000 and £40,000 per year if you consider the UK.

Salary of a Data Scientist

India: A fresher data scientist can earn between INR 8 LPA to INR 12 LPA, while professionals with experience in machine learning, Python and AI can easily fetch salaries of INR 15 LPA to INR 25 LPA or more, particularly in tech-driven industries. 

Globally: When considering the UK, the starting average salary can be between £35,000 to £60,000, if the guy has expertise in AI and machine learning. 

Final Thoughts

One of the major differences between a data scientist and a data analyst is focus. On one hand, data scientists use cutting-edge techniques to build predictive models and solve problems, while on the other hand, data analysts use existing data to spot trends and inform business decisions. Both of these positions are in heavy demand as businesses have now started to rely on data and statistics to make decisions.
