Difference Between Data Scientist and Data Analyst
The best way to find an answer to
the above question is, to look at the job descriptions, and also to check some
of the LinkedIn profiles. So, for this, I went through different LinkedIn
profiles and their job descriptions, and this is what I have found. Now, I
would also suggest you for the same, i.e. visit the LinkedIn profiles and
check the job descriptions.
- A Data Analyst needs to Collect, Explore, and Analyze data, and they also need to identify the trends and patterns, from the data that they have collected. And then lastly, they need to create visualizations and also produce reports.
- On the other hand, a Data Scientist, also needs to analyze the data, but they are more often required to Design, Experiment, and also test Hypotheses. And then, based on those outcomes, they need to apply different algorithms to build machine learning models, and then deploy those machine learning models to a production environment.
Skills Required
- Mathematics and Statistics.
- SQL Queries.
- Communication Skills.
You also need to master SQL (Structured
Query Language) to help you to assess and manage the data in the database,
so that you can use it to create, retrieve, update, and also delete records.
Tools used by Data Scientist and Data Analytics
Let us look at the tools that Data
Scientists and Data Analysts use it when they are doing their daily jobs. When they
are exploring data, especially when the data is not super huge. They use the
tools that we are familiar with, like Microsoft Excel because they are easily
accessible.
Career prospects
Salary Analysis
A junior Data Analyst has a starting pay at around 45k – 60k per month, and then their salary increases, as they progress with different tasks and responsibilities. So that a Senior Analyst, who is experienced makes about 1L – 1.2L per month. And as Analytics Manager, just like all managers, they are responsible to see a team of Analysts and their primary duties are, to manage and lead them towards achieving goals by implementing different analytical solutions, and so they make about 1.7L – 2.2L per month. And at the director level, they work more closely with the management, and more involved in their day-to-day operations and using data analytics in setting directions, and they make about 2.5L - 5L per month.
An entry-level Data Scientist makes around 45k – 60k per month. And once they're able to prove their value, the salary goes up to quite high like 80k per month. And a Senior Data Scientist can make up to 1.2L – 1.5L per month. Data Scientist is a new role that's constantly evolving. The benefit of gaining experience as a Data Scientist is, many companies don’t hire a Lead Data Scientists or Data Science Manager, rather the most Senior Data Scientist is usually made the team leader of a Data Science Team. The same is for a Data Science Director, the senior Data Scientists are promoted to a Chief Data Scientist, or sometimes Chief Data Officer, or Chief Information Officer. And therefore, their responsibilities and salaries are pretty much on par, with other C levels position like CEO and COO.What to choose between Data Scientist and Data Analyst?
For us, the key question here is, how do we choose between a Data Scientist or a Data Analyst position? But before that, let's try to understand the process of an analytics project. It usually covers three phases from Descriptive Analytics, Predictive Analytics, to Prescriptive Analytics. After having some research, I found that Data Analyst usually suits someone, who prefers to be more specialized in the industry, for example, Students/Professionals who prefer to work in the finance industry, they choose to become a Financial Analyst, or a Risk Analyst, or a Fraud Analyst. As they need to have a deeper understanding of those industries, to know where they can find the right data to help them to answer the questions.
Whereas, Data Scientists are someone more of a generalist. And they usually work in different areas, i.e. from agriculture, IoT, retail, eCommerce, to even epidemics. Data scientists work very closely with data analysts and use the outputs from their analysis, to build models and put those models into different applications.
