Can I Learn Data Science On My Own?

Do you wish to learn data science but do not know how to go about it? Can I learn data science on my own is something every self-learner asks himself before getting started?

and can you make a good career out of it? Read along to find out all the advice and guidance we have for you here.

You probably have heard a lot about data science but have minimal idea of what it is and how you can learn about it.

But shed away your worries as it is not very tough to understand, and all you need is a little patience and proper knowledge combined with some guidance, and you will be good to go.

So to answer the question as to what exactly data science is, let us look at its overall composition and meaning.

What is Data Science?

The Chief Economist at Google Mr. Hal Varian defines Data Science as – “The ability to take data, understand it, process it, extract value from it, visualize it, and communicate it.”

Most organizations need data scientists who can build complex authoritative algorithms in order to organize and synthesize bulk information at once, which is then used to answer any questions or to drive strategies in the organization.

The most critical factor to possess if you plan to enter this field of data science is to have immaculate technical knowledge and a result-oriented mind. With this, you can make a mark of your own in the career.

But with data science gaining so much popularity since its inception a few years ago, this has also become a very competitive field.

With such competition at hand and taking into consideration the career prospects, you may wonder if it is worth learning data science. Here is an analysis of this question.

 

Here is how you can learn data science on your own.

Can I Learn Data Science On My Own?

With the rising popularity of the job profile, there also is a surge in demand for learning data science.

Therefore some courses, tutorials, projects, and other resources are available both in online and offline education. Here are some that you can try out for yourself.

Learn Programming With Python

Learning Python is the first step when it comes to learning data science. If you have done programming earlier, then it is not so hard getting started with Python.

But if you have never done coding before, you need not worry. Python is one of the easiest programming languages to get started with.

There are a number of free resources available online. They will help you understand the basics of python.

Familiarize yourself with the syntax and structures. Practice as much as you can.

And once you are comfortable, start learning the data structures and algorithms.

These two are a must if you want to master any programming language.

Statistics and Mathematics

Data Science is all about analyzing data.

So you must have a knowledge of statistics and mathematics. So, start with the basic level statics that you have learned in your high school and then move towards an advanced level.

Learn How To Use Python for Data Analysis

Now that you are comfortable with Python programming and statistics, its time to dive deeper.

Start learning Python libraries like Panda and Numby. For that, you can take up, you can take Applied Data Science with Python Specialization from Coursera.

The goal is to have a deep understanding of some important Python libraries and data structures. And by the end of this step, you will accomplish it.

Learn Machine Learning

The next step is to learn Machine Learning. As the name suggests, Machine learning is a process by which a machine learns by itself based on the experiences and input feeds.

You can take up Machine Learning courses, which is the easiest way to get started. You will have a good understanding of Random Forest, Regression, Decision Trees, etc.

Work On Projects

As with any skills out there, practice on the things that you learned is also important in the case of data science as well.

And the thing to practice is to work on projects. Practice as much as you can.

By working on Project you learn to implement your knowledge to achieve different functionalities.

Online Certificate Courses

Tips For Learning Data Science

If you are well determined about learning Data Science and taking it up as your career, you also need to be prepared to continually keep brushing up your skills and proving to be exceptional in the field.

There sure is a lot of competition given the high demand for work as well as an excellent pay scale, and you must prove your mettle to stand out.

Whether you choose to take professional and paid courses with certificates or want to study Data Science on your own, there are a few tips that you must always keep in mind when learning Data Science.

R/Python + SQL

If you are not very good at coding and do not possess a lot of coding skills, then you surely need a lot of networking and other areas to make up for this hiatus.

In many cases, data scientists with weak math and minimal domain experience have always been carried by a strong ability to code.

Python is a great skill to possess, but R is a great fall back tool. It is only safe and commendable to have both. SQL is also vital for a Data Analyst.

Strong Math Skills

Having an excellent understanding of a few of the commonly used methods like generalized linear models, decision trees, K-means, and statistical tests is always better than having a broad spectrum knowledge of various models or specialization such as RNN as the former will always come in handier.

Is Data Science Worth Learning?

To answer this question precisely, yes, it is worth learning data science for many reasons.

This has now rapidly become one of the most sought after jobs because of the surge in demand.

The job really pays well even to a fresher, and as you become more and more experienced, the pay is bound to rise.

Despite industry verticals, forward-looking undertakings are contracting Data researchers and scientists to determine significant business bits of information and exceed expectations.

Data science is the amalgamation of your specific aptitudes, the logical inclination of the brain, and sharp business insight making it the activity job for the particularly gifted and driven having colossal development openings.

You will lead a different gathering of tech ability, business directors, bosses, and choose critical level suitable choices that will impact the fortunes of the association, putting you legitimately in the driver’s seat.

However, taking it up as a career should depend on how interested and driven you are for it and how well is your aptitude fit for working as a data scientist.

Make sure that you make up your mind to learn data science only if you are thoroughly inspired to and interested in it.
