Learning paths refer to a list of specific courses related to a particular profession or career interest. The path that you choose will depend directly on the skill sets that you will need to succeed in your respective career. Mastering and developing skills in the field of Data Science is the Data Science Learning Path. It is a high-in-demand path which many students are embarking upon to reach their goal of becoming Data Scientists.
The highly-structured module offers students a collection of resources that are comprehensive and valuable benefitting both professionals and those entering the field for the first time. For a student not familiar with Data Science or its learning path, it is easy to get confused by the options available. This blog post is designed to help you understand the basics to clear your confusion and help you make an informed decision.
What is Data Science?
Curious to know What is data science? If you were to look at the terms literally, it means the science that goes into studying data is Data Science. The reality is far from this simple explanation. Way back in 2010, Hugh Conway, the labour economics expert of the US, created the Venn diagram that captures the intricate and extensive nature of Data Science. Have a look at it below:
As you can see in the diagram above, there are three major areas or circles that cover Data Science:
- Maths and Statistical Knowledge
- Expansive experience
- Hacking skills
Data Science lies where the three circles overlap and create a confluence. The meeting of the first and third circles of Maths and Statistics and Hacking Skills is the area of Machine Learning. The negativity surrounding hacking has now transformed into ethical and unethical hacking.
A Data Scientist is required to have ethical hacking skills, with extensive experience in mathematical and statistical analysis. While traditional research and Machine Learning are important tools, the probability of a data scientist using their experience to turn from ethical to unethical is high. Learn more about the prerequisite of data science.
What does this denote in the real world?
- You cannot manage, read, or analyze Big Data without the help of Data Science and its branches. Tools, algorithms, principles and applications are used individually or in combination to interpret random data clusters.
- The science requires learning the processes for collecting, preparing, cleansing and analyzing the data.
- As a Data scientist, your job is to extract critical information from a collected set of data applying sentiment analysis, predictive analytics and machine learning.
- The information is then used to guide businesses to create strategies to help marketers and managers achieve organizational goals.

What does a Data Scientist do?
Businesses expect Data Scientists to solve an issue or provide an answer to a query by following the above-mentioned processes. Once valuable insights are gained, they can use robotic analytics and languages like Java to start creating and exploring programs that will ultimately lead a business to achieve its targets and goals.
Data scientists also employ different methods, like online experiments to ensure sustainable growth for businesses. Additionally, they can also help businesses by developing personalized data products that the companies understand, track and monitor unique patterns, customer requirements and other activities. The ultimate goal is always to help businesses make productive and profitable decisions. Learn more about the job description of data scientists.
What can you expect from the Data Science Learning Path?
A strong career for future scope of Data Science requires you to acquire critical skills in three departments which are programming, analytics and domain knowledge. The learning path will help you acquire the following skills:
- Strong knowledge of Scala, SAS, R and Python
- Understand different analytical functions
- SQL database coding experience
- Working with unstructured data from videos and social media platforms
- Machine learning to make predictive reporting and pattern discovery
- The program will cover inferential and descriptive statistics, natural language processing, model building and fine-tuning
The main focus of data scientists is statistical research and analysis, which is used to choose the right machine learning approach, after which the algorithm is modelled and prototyped for testing.
Using data-oriented technologies like SQL and Hadoop and making extensive use of distributed architecture, data visualization and statistical analysis, Data Scientists extract meaning out of data sets. The learning path will aim at producing skilled professionals who are experts in handling these aspects. They will be trained to switch their roles at any given point as and when required in the lifecycle of a Data Science project.
