Data Science Road Map

Entering the world of data science in 2024 requires a clear plan to navigate the changing technology and analytics landscape. This guide is your roadmap, designed to help aspiring data scientists. From learning basics to embracing the latest technologies, join us on a journey to acquire the skills needed to succeed in the growing field of data science.

What is Data Science

Data science is a diverse field focused on using data to answer questions. It involves collecting, cleaning, and analyzing data through techniques from statistics, mathematics, and computer science. The process includes tasks like exploratory data analysis, feature engineering, model building, and deployment.

Data science is interdisciplinary, requiring collaboration across various domains. Its goal is to extract actionable insights and solve complex problems, adapting to evolving technologies and methodologies. Different interpretations and applications arise as individuals and organizations emphasize specific aspects based on their goals.

How do we learn Data Science?

Data scientists who belong to various educational backgrounds should be more proficient in the following

1. Domain Knowledge
2. Math Skills
3. Computer Science
4. Communication Skill

1. Domain Knowledge

If you like to become a Data Scientist in the banking sector and you are aware of the banking sector such as stock trading, finance, and, so this will be more useful for you, and therefore, banks will give more preference to such kinds of applicants.

2.Math Skills

Among maths skills, Linear Algebra, Multivariable Calculus, and Optimization Techniques are very necessary to understand machine learning algorithms. Machine Learning Algorithms play a vital role in data science. Whereas, understanding statistics is very important for Data Analysis. Probability is also important for statistics and is one of the requirements for learning machine learning.

3.Computer Science

The Computer Science skills required for the data science aspirants are:

• Basics of Data Structure and Algorithm
• SQL
• MongoDB
• Linux
• Git
• Distributed Computing
• Machine Learning and Deep Learning

4. Communication Skill

In data science, you need to talk and write about your findings. After you figure out what the data is telling you, you have to share it. This might mean writing a report for your boss or team, making a blog post, or doing a presentation for your colleagues. No matter what, you always have to tell others what you discovered in your data science project. So, being good at talking and writing is really important if you want to be a data scientist.

5. Learning Resources

There are several resources and videos available online for a beginner to learn.
