A Step-by-Step Guide to Learning Data Science in 2024


In 2020, I enrolled in a Data Science Bootcamp, and to be truthful, my knowledge of the tech industry was quite limited. The only advice I received from seasoned professionals was to explore data science or software engineering. Honestly, software engineering felt overwhelming, so I decided to pursue data science instead.

I landed my first data science position in 2020, and it was both thrilling and enjoyable. Now, as I look ahead to 2024 and witness the growth of generative AI, I can’t help but reflect on how fortunate I was. I entered a less competitive field during a time when hefty salaries and remote work options weren’t the norm.

 

These days, companies are in a fierce race to stay ahead of the competition, and they’re spending big bucks to snag data scientists who can add real value. You’re not just up against 10,000 other candidates vying for that sweet remote gig with a juicy salary; you’re also facing off against generative AI, which can do your job for a fraction of the cost.

Pretty daunting, huh?

If you’re thinking about diving into the data science field, you might be feeling a bit lost and questioning if it’s even worth pursuing anymore. So, how do you tackle these hurdles?

In this blog, I’ll lay out a roadmap for mastering data science in 2024.

What Skills Should a Data Scientist Have?

Data Science Roadmap

Basic Principles of Programming

The initiation of your data science journey involves acquiring the essential principles of programming. This phase can be particularly intimidating, as it marks your entry into a new domain, requiring the mastery of a new language. It is crucial to recognize that ongoing learning is necessary for comprehending subsequent concepts.

Failing to solidify this foundational knowledge may lead to significant challenges in your future endeavors.

I recommend the following course: Learn to Program: The Fundamentals.

Data Preparation

Your interest in pursuing a career as a data scientist stems from your appreciation for the significance of data. Your primary focus will be on data cleaning, interpreting its messages, and leveraging these insights to inform data-driven business strategies.

Data wrangling involves the conversion and organization of data from its raw state into a structured format that meets specific requirements. Consequently, it is essential to acquire skills in loading data, sorting, merging, reshaping, and grouping it. Additionally, understanding various data types, such as strings, is crucial.

This phase of your data science journey requires extensive practice. The more you engage in this practice, the more proficient you will become.

I recommend exploring the following course: Data Science Wrangling.

Data Representations

After mastering the art of cleaning and transforming your data into the format you need, the next exciting step is to visualize it in a way that supports or challenges your hypothesis. This phase of your journey doesn’t require weeks or months of learning, but it’s crucial for effectively sharing your insights with stakeholders. Crafting visualizations from your findings is a key part of the data science process, allowing you to express your creativity. With some practice and experimentation, you can pick this up in just a week. I highly recommend checking out this course: Visualizing Data with Python.

Mathematics, Probability Theory, Statistical Analysis

Many individuals fail to recognize the significance of comprehending data science through the lens of mathematics. Numerous courses tend to omit essential mathematical and statistical components from their data science curriculum, yet these elements are fundamental to the discipline. Consequently, acquiring this knowledge is one of the most beneficial steps you can take for your career.

It is crucial to familiarize yourself with topics such as linear algebra, numerical analysis, descriptive statistics, confidence intervals, t-tests, and Chi-square tests, among others. Mastery of these subjects will enhance your analytical capabilities and is vital for validating your hypotheses effectively. To achieve proficiency, it is advisable to practice with various datasets that you can analyze.

I recommend enrolling in a course series that thoroughly covers linear algebra, calculus, probability, and statistics: Mathematics for Machine Learning and Data Science Specialization.

Machine Learning

The two above courses both dive into math, probability and statistics for machine learning and data science which is a good transition for the next phase of your data science journey – machine learning.

In your data science career, you’re going to want to uncover complex patterns and the different relationships in your large dataset. However, statistical analysis may not always be your best option and you will need to leverage machine learning algorithms. Not only will you be able to uncover these insights in a shorter period, but they will also be accurate predictions that you can use down the line during your decision-making process.

Your journey to learn machine learning will include type 1/2 error, train-test split, AUC ROC, confusion matrix, cross-validation, and more. All of these topics will help you in your model selection decision.

Here is a link to a specialized course that I highly recommend: Machine Learning Specialization.

Advanced Neural Networks

There is still much to learn; it is important to recognize that the journey will not be easy. We are now delving into deep learning, a branch of machine learning that trains computers to undertake tasks similar to those performed by humans. Artificial intelligence is currently reshaping numerous industries, and to excel as a data scientist, it is vital to grasp how this transformation is occurring. Acquiring knowledge in deep learning is the key. You will need to study deep neural networks, including their design and training, as well as identifying architectural parameters and applying your deep learning insights to real-world applications. Utilizing best practices and strategies will aid you in becoming a proficient deep learning expert as a data scientist. I highly recommend this specialized course: Deep Learning Specialization.

Generative Artificial Intelligence.

While it may appear that there is already an abundance of content to master, the aforementioned insights will assist you in maintaining a competitive edge in the global market against other professionals.

Another challenge that data scientists must address in 2024 is how to stay relevant amidst the increasing prevalence of generative AI. If you are under the impression that you need to focus solely on aspects of data science that generative AI tools, such as ChatGPT, cannot perform, it is advisable to reconsider that perspective. Instead of viewing these tools as adversaries, explore ways to incorporate generative AI into your data science practice to further your career.

Utilize these advancements to your benefit and seek to understand them. For instance, familiarize yourself with PandasAI; rather than perceiving it as a potential obstacle to securing your ideal position, embrace it as an opportunity to enhance your resume and expand your toolkit, thereby demonstrating your capabilities to prospective employers.

Concluding remarks

I trust that this blog has provided you with insights on navigating your data science career during a period of intense competition, not only from fellow data scientists but also from generative AI technologies.
