About Data Science

The core idea behind data science is to extract information that can be considered actionable from a set of raw data. Information about a person’s choice, basic details like name and contact information, or even the likes a person gives or receives on social media are all part of the data generated and stored over the internet. Organizations collect a large amount of unstructured data, which is added to the data lake. But, differentiating between the important and redundant sets is the most crucial task. This structuring and processing of the data are done with the help of data science.

Data science is a broad-spectrum and multidisciplinary field. The subject implies scientific methods to find and understand patterns that are a given with big data. While many interdisciplinary subjects overlap with data science or use part of the techniques, the course itself is interesting and can be a gateway to more professions.

Often people confuse the role of a Data Scientist with that of a Data Analyst. While both these professions deal with understanding and structuring data, a Data Scientist focuses primarily on arranging the data to make sense and creating predictive models. In contrast, a Data Analyst finds the answers to the questions raised by data science.

    While data science is a technical subject, the job that entails the specialization of a Data Scientist also requires you to have certain soft skills or non-technical skills. These are necessary when you have to cater to large data. You need to be able to:


    • Communicate properly: Data science is a technical subject, and hence, jargon is inevitable. But, your colleagues are not all data scientists, and since you need to work with other teams to generate revenues, you need to be able to simplify the reports for everyone’s comprehension.
    • Act as part of a team: Data science is not reliant only on a Data Scientist. Some analysts and engineers have to work on the same sets of data. Hence, coordination and the capability to be a team player are essential.
    • Organize effectively: Companies hire professionals who are well-acquainted with computers and statistics. The other quality sought in the data science professionals is being organized in the tasks given.

    What is the age limit for studying data science?

    There is no such upper limit regarding age to study data science. This is a vast field, and many companies are constantly looking for competent Data Scientists. Statistics predict that the need for Data Scientists and other data-relevant fields will increase exponentially in the near future. And, there are not many people to fill up the roles. Hence, getting an additional degree or diploma in data science is beneficial.

    Is it possible to pursue data science even without a STEM background?

    Data science is a technical field, and having opted for science subjects and computer applications in high school is essential. Suppose you have not pursued computers or mathematics and statistics in your academic years. In that case, you need to show that you have taken those classes after school years to be considered eligible for studying data science.

    What is the difference between a Master’s degree and a postgraduate diploma course?

    Both MSc in data science and a postgraduate diploma (PGDM) in data science are courses that an individual undertakes after the completion of their undergraduate or bachelor’s degree. The core difference lies in the credits that these courses offer, the duration, and the specialization that students can opt for. The master’s degree is a full-time course with 180 credits. The PGDM is a part-time course with 120 credits. While both are specialization courses, the PGDM focuses on improving skill sets.

    Which is better, being a Data Scientist or being a Data Analyst?

    A Data Scientist creates questions through collected data, and a Data Analyst finds the solutions to those questions. Since both these fields are complementary to each other, there is no question of stating which is better over the other. 

    Is it possible to pursue a Ph.D. post PGDM in data science?

    Yes, getting a Ph.D. in data science is possible even though you have opted for a postgraduate diploma course. You just need to clear the CSIR-UGC NET Exam. 

    What is predictive analytics?

    Predictive analytics is a part of data science and data mining. With predictive analytics, you can teach the computer to go through the data history, track the patterns and the parameters that act in correlation and then predict an outcome. For example, if a power grid is shown to malfunction every time a particular sensor reaches a particular temperature. In that case, the machine will be taught to send notifications every time that sensor is at risk of reaching that particular temperature. This aspect plays a vital role in risk assessment and disaster aversion.

    What programming languages will best help in learning data science?

    Programming language is the language that computers use to communicate with each other. Every student who studied computers in school has been taught DOS and C or C++. These languages, though older, are not very reliable when it comes to processing data. Hence, it is essential to polish the language skillset. Some of the best languages are:

    • Javascript
    • Python
    • Go
    • Java

    Is data science a difficult subject?

    The difficulty level of data science as a subject depends on the learner’s capability and the ability to grasp concepts. Being a technical domain, data science might seem to be a difficult subject on paper. Still, given the number of students enrolling in data science, it can be said that the subject is interesting. With practical knowledge along with theories, data science can be fairly easy to master. 

    What is the function of SQL in data science?

    Structured Query Language or SQL is a programming language that is used to retrieve and store data. Since data science is all about collecting and analyzing data, the retrieval and storage part is vital in generating historical datasets for the machine to upgrade itself. 

    What are the basic data science concepts that beginners should know?

    Data science is primarily dependent on statistics and machine learning. Hence, proper knowledge about both these core components is essential. As a beginner, it is expected to know the following statistical disciplines:

    • Descriptive Statistics
    • Probability
    • Dimensionality Reduction
    • Central Tendency
    • Hypothesis Testing
    • Tests of significance
    • Sampling theory
    • Bayesian Statistics

    Can a data science course be self-taught?

    Technically yes, data science can be self-taught, and people who have expertise in the domains of machine learning and programming languages can look up various videos and tutorials, and most of them are available for free. But, the certification is essential for getting a proper and well-paid job for companies would seek academically sound students over self-taught professionals.
