The Ultimate Guide To Learning Data Science

Data science

If you’re trying to break into the data science industry, now is the best time to do it!

To jump into a new field, especially one as interesting and multi-faceted as data science, is adventurous. Some claim that learning data science takes between 3-8 months. While others assert that it only needs 6 months of practice and a weekly time commitment of four to five hours. But, in the end, it depends on your focus, patience, and practice level (FPP). Your experience and educational background doesn’t count much.

There are a plethora of free data science courses available to give a good start to your data science journey. Unfortunately, the majority of those who attempt to learn data science fail. They fail because their approach is riddled with errors that impede their advancement. Finding the correct approach is crucial for learning data science quickly and successfully.

Introduce yourself with Data Science

The first step is to understand what data science means. It is also important to know the different fields that come together to form it. Jumping into data science without any shape or form is disastrous and may leave you with regret in later stages. Not enjoying the process after putting in a few months of effort is a devastating personal setback. There are a lot of free data science courses and materials to brief you about data science as a whole.


Select the role

This is yet another important factor that needs to be taken into account when you are starting to learn data science. Different job responsibilities are available in the data science sector, including that of a data scientist, machine learning expert, data engineer, data visualisation specialist, and many others. Aiming for one role could be easier than another. Depending on your tastes, educational background, and work experience, find that one role


As a beginner, you must study the important tools to learn data science. 

Listed below are core tools of data science:


  1. Statistics:

Statistics is the process of analysing historical data, like customer search history. Statistics are at the core of sophisticated machine learning algorithms, capturing and translating data patterns into actionable evidence. High school level of Statistics is more than enough for this.


  1. Calculus for Machine Learning

Linear algebra and calculus are two areas where machine learning theory converges. Machine learning is fundamentally based on mathematics. It helps in the creation of algorithms that can learn from data and produce accurate predictions. Again, high school levels are more than sufficient for this.


  1. Programming: 

Last but not least is programming knowledge. Data Science and Data Analytics are fields that join programming, mathematics, and business. Following are the essential ingredients to learn Data science.


  • Advanced Microsoft Excel:

Excel’s vast feature set makes it an excellent tool for cleaning data. It is one of the most widely used tools for data analysis. Its built-in pivot tables are the most widely used analytical tool. You can analyse data in a variety of ways using Microsoft Excel. You can analyse using conditional formatting, ranges, tables, text functions, date functions, time functions, financial functions, financial functions, subtotals, quick analysis, formula auditing, inquire tool, what-if analysis, solvers, data model, PowerPivot, PowerView, and other Excel commands, functions, and tools.


One should learn MS Excel up to the level (basic to advance) as there is its need in the role they want to play.


  • Python/ R:

Python is an interpreter-based language as it reads the lines of Python code and interprets them. For many data science projects and applications, it is one of the best languages utilised by data scientists. For dealing with arithmetic, statistics, and scientific functions, Python offers excellent capabilities.

R is modified to create statistical models for analysing a lot of data. R includes static visuals that provide high-quality data visualisations, which is why many data scientists use it while studying data. Additionally, the programming language contains a large library that offers interactive visuals and facilitates the analysis of data visualisation and representation.

Any of these 2 languages is enough for landing a successful career. However, Python is the most opted language because of its being comparatively easy and more learner friendly.

  • SQL:

SQL is used to obtain and modify data from databases. For handling data stored in relational database management systems, programmers use SQL or Structured Query Language. Since these databases house almost all structured data, learning SQL is probably a good idea if you want to play around with data.
