It’s going to be rather interesting to see how the dynamic field of data science changes over the next 2-5 years. That is so because the supply of proficient data scientists can hardly catch up with the demand for data science talent. It is high time that you start to learn how to become a data scientist because according to reports, the data scientist role is one of the highest-paying tech jobs in India.
I know it is easier to say, “Become a data scientist” but without proper guidance, it is a hard task. But fear not, this article is for you. I will be covering ways in which you can become a data scientist in 3 months. So, let’s get started.
Introduction to Data Science
Data science is like being a detective for numbers and information. Imagine you have a big pile of puzzle pieces (data) from different sources, like social media, sensors, or online shopping. Data scientists are like puzzle solvers who carefully study these pieces to find hidden patterns, secrets, and stories.
They use special tools to put the pieces together, analyze them, and figure out things like why people buy certain things, how diseases spread, or what makes a video go viral.
Their findings help companies make better decisions, data scientists discover new things, and even help predict future events based on what happened in the past.
Just like detectives, data scientists use their skills to solve mysteries hidden in the data and uncover valuable insights that can change the way we understand the world.
Questions are asked and answered with data. When you dig deeper, it becomes clear that data science is not devoid of human experts. Instead, it’s a tool for human experts, just like mathematics, simulations, or theory.
Become a Data Scientist in 3 Months
To become a data scientist in just three months is a challenging task, as data science is a multidisciplinary field that requires a strong foundation in mathematics, statistics, programming, and domain knowledge. However, if you’re dedicated and focused, you can make significant progress in this time frame by following these steps:
Gain qualifications:
In terms of getting hired, a bachelor’s degree in computer studies, economics, finance, business studies, statistics, or mathematics is certainly considered an advantage for a data scientist’s profile.
However, more and more employers are willing to waive such requirements in favor of relevant skills and real-world experience.
The typical data scientist in India has taken at least one certified online data scientist course, which brings forth the increasing importance of online data science training – not only when it comes to learning the fundamentals but also for acquiring the latest in-demand skills.
Data scientists with 5 years of experience are estimated to be earning INR 60 – 70 LPA. However, there are plenty of data science opportunities for skillful beginners in the field too.
Learn pre-requisites:
The must-have skill set for a data scientist in India includes proficiency in Excel, good practical knowledge of statistics and mathematics, a solid basic linear algebra, and an understanding of algorithms.
More advanced mathematics may be required for certain positions, but this is a fairly decent starting point. Also critical is understanding the concept of machine learning. As the field advances, basic levels of machine learning will become a standard requirement for data scientists.
Learn to code:
The best data scientists must know how to manipulate code in order to direct the computer on how to analyze the data. Scripting languages such as SQL, Python, and R are great places to start.
While Python holds the lead in popularity in the US and Europe, it shares the winner’s place with R in India. But how do you acquire all of this if you’re starting from scratch?
Well, luckily there are many options today to learn data science. You can start a qualification program or study with private tutors, for instance. If going back to school is not on your agenda though, online educational platforms can be the best way to begin your professional journey.
Practical learning:
If you are a college student or a fresher, try to get a data science internship even if it’s unpaid. Your objective is to gain industry experience that you will later apply in your permanent data science job.
Create a good GitHub repository, upload your own data science projects, and work there. Also, put your GitHub link in your LinkedIn profile. It’s a good way to showcase your work to prospective employers.
Consider participating in online data science competitions. This will help you validate your learning and also get noticed by employers if it is a sponsored competition.
Attend local data science meetups that are taking place regularly in data science hubs like Bangalore, Pune, and Delhi NCR, and try to network with the people. This can truly help you create more opportunities for yourself.
Divide and Conquer:
In addition to this, we came up with a detailed breakdown as the saying divide and conquer where we divided the subject into parts and mentioned the time required to complete it as that can yield better results:
Learn the Basics (1-2 weeks): Start by understanding the fundamental concepts of data science. Learn about statistics, probability, and linear algebra as they form the backbone of data analysis and modeling. Online resources, tutorials, and introductory courses can provide a solid foundation.
Programming Proficiency (2-3 weeks): Gain proficiency in a programming language commonly used in data science, such as Python or R. Focus on libraries like pandas, NumPy, and scikit-learn (Python), or dplyr, ggplot2 (R) for data manipulation, analysis, and visualization.
Online Courses (6-8 weeks): Enroll in comprehensive online data science courses. Platforms like Coursera, edX, and Udacity offer structured curricula covering topics like machine learning, data analysis, and data visualization. Notable courses include the “Data Science Specialization” on Coursera and the “Introduction to Data Science” on edX.
Practical Projects (4-6 weeks): Apply what you’ve learned by working on real-world projects. Choose datasets related to your interests and build end-to-end data science projects that involve data cleaning, exploration, feature engineering, modeling, and interpretation. GitHub is a great platform to showcase your projects.
Machine Learning Mastery (3-4 weeks): Dive into machine learning techniques, focusing on supervised and unsupervised learning. Learn about algorithms such as decision trees, linear regression, logistic regression, clustering, and more. Understand how to evaluate model performance and fine-tune models for better results.
Capstone Project (2-3 weeks): Create a significant capstone project that demonstrates your skills. This project should involve complex data analysis, machine learning modeling, and insights generation. It showcases your ability to tackle end-to-end data science challenges.
Networking and Online Communities: Join data science communities like Kaggle, Stack Overflow, and LinkedIn groups. Engage in discussions, ask questions, and learn from experienced data scientists.
Join the community:
Keep an eye out for thought leaders from the industry, engage in industry blogs and websites, ask questions, and stay on top of current news and theory.
So what’s the takeaway here?
If you have the skill base to become a data scientist, you’re halfway there. Data science is certainly not for everyone, but for the interested and dedicated, it can be incredibly rewarding, while offering the chance to create a serious impact in today’s world. Here’s a universal data scientist profile that appears to be taking shape right now:
- A unique programming language toolbox desired across locations and industries
- Preferably a Master’s degree, or a certification/Bachelor’s degree with proof of practical ability
- A confident, learning-on-the-go attitude
