beginner’s guide to data science

In recent years, the data science industry has become one of the fastest growing areas of employment, with demand far outstripping supply. As more and more companies realize the tremendous value that can be gained from gaining deep insight into their operations by studying data, the demand for data scientists will continue to increase globally.

A role that can be applied to almost all sectors and companies

In addition to the relative lack of data scientists around the world, another factor that contributes to the high value of data science is the fact that the principles can be applied to almost any type of company. From agriculture to technology, from manufacturing to service companies, almost all companies can benefit from having a bird’s-eye view of their processes and studying the data they produce.

As the demand for data scientists continues to grow and more companies realize the value of studying their data and the transformative effect it can have on profits, a job as a data scientist will continue to be one of the best tickets in town. : but what is a data scientist and what do they do?

What is a data scientist?

In plain and simple terms, a data scientist is much like an analyst who uses his knowledge of technology and science to extract information and improve the efficiency of the information generated by companies and individuals. As the lines between the real and virtual worlds continue to blur, we are producing more data than ever before, data that can be interpreted for all sorts of uses and outcomes.

In business, this data (or, in another way, this digital information) can provide unimaginable depth of reporting to internal processes. The digitization of business has already been underway for many years, but only recently have companies realized that by studying this internal data, they can drive greater efficiency and eliminate waste. With almost every business these days now inherently dependent on the web, computers, and technology, the knowledge and skills of a data scientist can be applied across large sectors of business and industry.

How to train as a data scientist

Although it might theoretically be possible to train as a data scientist, for most people, the fast track and most successful way to get a position as a data scientist is to learn at university. These days, there are a wide variety of educational establishments that offer both online and offline courses in the area of ​​data science; For example, you could study for a master’s degree in data science.

It’s also worth remembering that if you’re looking for a career change or just want a little more job security, online training might be your best bet, allowing you to study in your own time and at your own pace without unduly disrupting or causing problems. in your current job. Furthermore, studying online is also usually considerably cheaper than traditional real-world courses.

Career Prospects for a Data Scientist

Unsurprisingly, with basic data science skills applied to so many different industries and sectors, the demand for experienced data scientists remains buoyant. The industry is one of the fastest growing in the entire computing and IT sector, with professional aspects and longevity currently looking great.

Salary Outlook for a Data Scientist

All jobs vary and the salary you can expect working in the data science sector will also vary from country to country. Nonetheless, an experienced and trained data scientist would expect salaries at the higher end of the tech industry.

Skills that Help as a Data Scientist

The data science course or data analyst course will of course help you hone the skills needed to work in data science; however, it still helps if you have some underlying aptitude and skills. As a general rule, most data scientists need skills in a relatively diverse range of topics, including (but not limited to):

Statistics and Reporting – You will definitely need a strong foundation in statistics, including knowledge of hypothesis testing and concepts like linear regression.

Mathematics: Unsurprisingly, much of data science is based on mathematical principles like calculus and algebra. Many of the most successful and in-demand data scientists have at least a basic math qualification, but more have education up to a Ph.D. level in Applied Mathematics or similar.

Programming: R is a specific programming language used in data science, so knowledge of this will be invaluable, as will being able to write in Python.

Be comfortable handling data from multiple different sources – As a data scientist, you will typically pull data from many different places, and you should be comfortable organizing these huge amounts of information.

Networking: The old saying, “It’s not what you know, it’s who you know that matters” is as applicable to data science as it is to any industry. Having good networking skills and the ability to meet, greet and talk to a wide range of people will help you get ahead.

Presentation Skills: Collecting and figuring out is only a small part of the story when it comes to the job of a data scientist; You must also be able to present your findings in an interesting and engaging way to the stakeholders involved in the work. Having good presentation skills will be an added asset for this part of the job.

Knowledge of commonly used software: Ideally, you’ll be well-versed in software tools like Tableau and Plotly, which are commonly used by data scientists for visualization purposes.

Where will a data scientist typically work?

As mentioned above, the demand for data scientists is currently enormous, so it’s likely that you’ll find yourself working in an equally massive diversity of jobs and for companies in entirely different industries. Companies in all industries increasingly rely on the data they collect to make important strategy-driven decisions about their future direction, so you could be working for a manufacturing company one day or an IT service provider one day. following.

Is the job of a data scientist just a flash in the pan?

Very, very unlikely. When you consider that nearly every business exists to make a profit with as little outlay as possible, it’s almost obvious that a professional with the skills and knowledge to reduce overhead and improve efficiency will continue to be in high demand for the foreseeable future.

By working as a data scientist, you will have the potential to make a real difference to companies, helping them streamline operations and make better decisions for their future direction. People with those kinds of skills will surely continue to be a priority.

What is the future of data science?

As with many computer-based and web industries, there are compelling reasons to believe that much of the technology that will be used in the future of technology has yet to be invented. Certainly, very exciting advances are being made with cutting-edge technology such as Artificial Intelligence (AI) and Machine Learning (ML), both of which are ideal tools for interpreting the masses of data that data scientists commonly deal with. Also, technology like blockchain is already having an impact on the industry.
