Today, we will cover the following topics and learn about the industry demand for data science and the skills required to have a successful career in this domain.
Data science as a field is interdisciplinary and is about the scientific approach in processing large data requirements. It involves several scientific techniques and theories that have been derived from various fields such as statistics, mathematics, information science, computer science, and domain knowledge.
Take a look at Data Science Jobs and Careers:
Data Science Demand
Data democratization is transforming our world in a fundamental way. Every industry as well as governments around the world are acting on a wide variety of data sources. Businesses have undergone major transformations with insights and predictions powered by data.
The aforementioned changes led to the requirement for data science professionals across various industry verticals that had rapidly shifted. Businesses are having to rethink hiring, training, and partnerships. The latest demand is for a group of professionals who are skilled in data, analytics, machine learning, and artificial intelligence.
These days, data science may seem like a highly employable and appealing profession. However, instead of looking at what’s trendy, it is essential to have a deep understanding of the shifting demands of the current job market.
As per a report by the U.S. Bureau of Labor Statistics, by 2026, the increasing demand for data science will create approximately 11.5 million job openings. Data science is going to be a leading emerging domain in the coming future.
After the United States, India is the second most prominent hub for data science developments. This demand has introduced a rapid surge in the data science course providers.
Data Science Course Eligibility
To be able to meet the explosive demand for data scientists, higher education needs to be nimble and responsive while certifications, graduations, and executive-level programs have to be responsive to the requirements of the workforce.
So, who can learn data science? The answer is simple, anyone who is willing to learn data science, be it a newcomer or an experienced professional. Engineers, software and IT professionals, and marketing professionals alike can sign up for part-time or external data science programs. Now, let’s take a look at the eligibility for data science courses.
To take regular courses in data science, knowledge of basic high-school-level subjects are the minimum requirement. As data science is, loosely, an amalgamation of the concepts derived from computer science, mathematics, and statistics, learners should aspire to, first, earn a degree in one of the STEM (science, technology, engineering, and mathematics) backgrounds.
Studying computer programming in high school can benefit you in the future while pursuing data science. Based on the subject knowledge in programming, statistics, or machine learning, learners become experts in the practical implementations of data science methodologies.
Individuals from other streams, such as business studies, can study pertinent courses in data science. Likewise, anyone with a degree in business administration, such as a BBA or MBA, is also eligible for higher studies in the data science domain. These professionals can go on to work in the capacity of executives and be responsible for generating customer relationship management (CRM) reports, business-related data quality assessment (DQA), and management information system (MIS).

Data Scientist Qualifications and Skills
Let’s take a look at some of the data science course eligibility criteria. For admission to a data science course, generally, the following qualifications are required:
- Degree: A graduation from the STEM stream
- Mathematics: It is the heart of machine learning, data science, and data analysis because the models are created by processing the data of mathematical algorithms. Mathematics includes algebra, statistics, calculus, differentiation, probability, arithmetics, geometry, etc.
- Statistics: This subject helps one understand, analyze, and derive a conclusion from the data.
- Data Visualization: After data access and retrieval, data visualization is performed and presentation is done with R and Tableau.
- Exploratory Data Analysis: It involves exploring Excel and databases to derive useful information and conclusions and learn from data attributes and properties.
- Hypothesis Testing: Hypothesis formulating and testing are applied during case studies for solving real business problems.
- Programming Languages: While coding is not an absolute criterion for eligibility to sign up for data science courses, knowing programming languages, such as Python, Java, and Scala, will surely benefit the learners.
- Database: A good understanding of databases is also highly desirable.
The Science Behind Data
The field of data science highlights the processes involved in methods, algorithms, and systems, with the help of which knowledge and intelligence are derived from a pool of structured and unstructured data. Several data-driven initiatives like big data, data mining, machine learning, and AI are catered to by Data Science.
Data science could be considered as a concept that unifies statistics, data analysis, and methodologies to perform analysis and make sense of real events with the help of data.
