Career in Data Science 101
Data Science relies on investigation, helping you uncover usable insights like trends, consumer behavior, retention, usage, etc. The investigation is aided by tools, algorithms, statistics, mathematics, and machine learning processes, as well as technology.
Example? Take Google, Amazon, or Flipkart. They record and store cookies and your personal data like location, gender identity and location to improve your consumer experience. The same engine also shows you products or services you are likely to use. So, businesses today use data science to outperform and increase retention through smartly fixated business choices.
Data Science propels automated methods to assess and analyze vast volumes of data, extracting insights to progress the informed business planning.
Now, when you are looking at a data science degree in the context of academics, you have to learn what entails this interdisciplinary discourse. Since data science requires a spectrum of skills and tools, you might ask – are you into maths or stats or are you into software engineering.
The right way to approach the definition of a data scientist would be – a data scientist is likely to be better at stats than a software engineer while being better at software designing than a statistician.
As you have gathered already, data scientists are analytical experts who are scientists and technical experts. They have the tenacity to conduct holistic research and the technical skills to solve complex issues.
They don’t just understand the language of data, they have mastered the art of storytelling via data. This has made data mining, data management, and data refining more comprehensive for stakeholders and management, helping them make informed choices.
Here are some of tasks they normally handle:
- Framing and identifying data analytics related problems that directly impact the clientele and the company.
- Collecting, transforming and cleansing the unstructured and structured data acquired from different data sources.
- Building statistical models and automating machine learning algorithms to commit in-depth analysis of the data processed.
- Interpreting data models to locate patterns or address solutions and opportunities for the better retention and growth.
- Communicating the discoveries comprehensively, more like storytelling. This helps the stakeholders in having a clear purview of the situation.

How Hard Can it be to Become a Data Scientist?
To answer that question, you need to know the purpose data scientists and a data science degree serves.
To reiterate, data scientists extract, wrangle, pre-process, and scrutinize data. After this, they make supposed outcomes and predictions. So, the purpose of a data scientist is to derive conclusions through which they can assist the companies in making informed decisions.
Now, what to learn to become a data scientist? It entirely depends on the kind of data scientist you want to be. Many standard courses include advanced curriculum which you might find redundant. Next would be the academic discipline you are hailing from. For instance, if you are coming from disciplines like maths, data analysis, stats, and applied computer science, your transition would be fairly easy.
Most of the data science projects that you will come across will involve design algorithms, various statistical techniques which might or might not require prior mathematical or statistical knowledge. So, as a data scientist you will be coming up with original models which can either be based on statistics or completely data driven.
Although data science relies on a steep learning curve, it is not entirely unfathomable. Even if you do feel the inadequacy of not being able to keep up with data science, you should at least know why this job profile can be challenging.
What are the Data Scientist Qualifications?
Here are a few key things you should be wary about before deciding your career as a data scientists:
- Data science deals with variations and given that it’s a nascent field of study, you’d be running a trial and error method with your acquired methodologies. But that should not just limit you to deny this pursuit, be open to challenges.
- Managing bulky data is tiresome. Data you collect might not be structured which adds to your challenge. But that naturally falls under the responsibilities of a data scientist. But if, as a data scientist you have prior knowledge of tools like Sparks or Hadoop, then you can calibrate your workflow.
- As mentioned already, data science is an interdisciplinary field. So, the academic appetite for this discipline requires you to be more versatile. This is also why most data scientists hold expertise over quantitative fields like stats, finance, or natural sciences.
- You need to have domain knowledge that can only be acquired through experience. Domain knowledge is required to locate variables and develop models in the context of your problem. Domain knowledge is imperative since it also helps a data scientist to re-evaluate and eliminate biases.
- Mathematical concepts can be daunting but that lays the foundation of data science. Concepts are then implemented in practical fields. So, it remains that your theoretical concept would require an auxiliary implementation which otherwise will vaporize.
A number of universities have started to address this governing concern. AnalytixLabs is one such institute that has adapted to this demanding learning curve.
