When you hear the term Data Scientist – most of you think of geeks who know computer science, math, algorithms, and who knows what else. To be honest, there is truth in it – but above all, it is a sought-after, dynamic, and well-paid job. Therefore, in our 2023 Guide, we will try to answer the question: are online Data Science courses worth your effort and money. We assume that the answer to this question may be relevant to people who would try their luck in this profession.
What Is Data Science And Does It Pay Off?
Recent research conducted in the United States and many Western European countries has shown that the profession of Data Scientist is among the most desirable ones. That is not at all surprising if you consider the average salary – which in the US is about 115,000 dollars a year. However, even today, it is not clear to many what a Data Scientist is. What everyone says is that this profession is difficult to describe – but it is interesting that most of these experts can easily start working for Mark Zuckerberg’s company. So what is Data Science? It is a multidisciplinary profession that combines computer science, mathematics, statistics, analytics, programming, and much more. For some people, this sounds too difficult. While nothing is that hard if you love what you do – Data Science isn’t just for everyone. Like any other profession, it requires dedication. The fundamental prerequisite for success in this field is that you must be interested in all these areas. So, you should be interested in analytics, you should love “mining for data” so you can get the most out of them.
Who Are Data Scientists And What They Do
Did Facebook ever recognize your photo, or did Amazon recommend you a new book to buy? We’re sure you already know what we’re talking about. These things are the result of collecting data about users, their hobbies, interests, etc. In that case, the Data Scientist profession slowly becomes more clear to you. But who are the people involved in this business? Among the employees in this branch, you will find programmers and mathematicians – but also psychologists, electrical technicians, biologists, surveyors, financial experts, linguists, etc. Data science covers an extremely wide range of areas where we can use it. With the help of data, math, and programming – we can determine the mood of people on social networks, but also approve bank loans, plan marketing campaigns, conduct genetic research, construct intelligent robots – or predict the election results. All this is what we call Data Science today.
Data Science Online Courses: Are They Worth It?
In most countries, there is still no faculty for Data Science – but this area is studied at some other faculties such as IT, etc. Therefore, it is not surprising that more and more young people who are interested in this profession of the future – are turning to self-improvement through online courses. However, although many people wonder whether such courses are worth the money and effort invested – the answer is YES. There are many reasons for it – and we will note that data science experts can be employed in many different industries and fields and they are also very well paid.

The more you know, the better your chances are for a well-paid job – and we must note that salaries in this area are excellent and often higher than in the rest of the IT profession.
Social Networks As A Learning Tool
In addition to books, courses, and blog posts, there is another rather good way to get relevant information and knowledge – and that is social media. LinkedIn, Reddit, and Twitter are my favorites so far, though, of course, there are others. This way, you can follow the leaders in this field, be always up to date, connect with people of similar interests, share experiences and knowledge, and gain more.
Scope Of Work Data Scientists Do
This is a very broad term that is the most difficult to explain. Namely, their work can range from data engineering to classic software development, machine learning, statistics, etc. Some even describe data scientists as people who know statistics better than any programmer – but also as people who program better than any statistic expert. Although people say this as a joke, it is not far from the truth. A data scientist must have good knowledge in both of these areas. These experts must have good programming knowledge, knowledge of mathematical algorithms, probabilities, and statistics. Therefore, it is quite natural that software engineers and math experts are mostly engaged in this business. However, you will find people from other professions also engaged in it.
Tools Used By Data Scientists
Most of those who are familiar with the term Data Science have heard of tools such as Python. However, that is certainly not all that they can use. The tools available today are numerous, and one should not cling to a particular choice of tools. It is best to choose a specific set of tools and learn how to work with data. Experts advise you to learn the basics of probability and statistics, linear algebra, machine learning, and programming. Also, you can choose a set of data processing tools and practice what you have learned. Plenty of data is available – find an interesting problem and work on it. Also, connect with people. The data science community is quite large, and you can surely find your place “under the sun”.
If you have been thinking about directing your career toward a profession like Data Scientist, we hope this text has clarified, at least, some of the things that interest you. We have to emphasize once again that this is not exactly a job that everyone can do – and you will need a lot of learning and dedication on this journey. If you have already made a decision, we wish you good luck.
