How hard is data science?

In data science, professionals use computer programs, complex algorithms and statistics to get insights, solve problems and make informed business decisions. Therefore, businesses can rely on something other than gut instincts in order to make essential business decisions. Some methods and techniques used in data science may include mathematical modelling, statistics, and ML, to name a few. This may cause you to think if data science is hard. Let’s find out.

Nowadays, data science is so in demand that all types of organisations and companies hire the services of data scientists. For example, today’s big players in the world of IT services have employed data scientists. Some of these giants include Microsoft, Amazon, Facebook, and Google, just to name a few. 
These companies hire the services of data scientists in order to know more about customer behaviour and other things that can help them make better business decisions. In the same way, government agencies also use the services of data professionals. These agencies include some of the top names, such as the CIA and NSA.

If you want to get a basic idea of the difficulty of learning data science, you may want to know about the programming language used in the world of data science. Let’s talk about them one by one.

  1. Python 

In the data science field, Python is a popular programming language. Since this is a simple and flexible language, it has become popular among programmers. You can use Python to develop websites and programs. Apart from this, this programming language has everything you need to operate a machine learning system.

Another name on this list of programming languages is R. This programming language is an ideal choice when it comes to predictive and statistical analysis. 

  1. MATLAB 

Matlab is short for Matrix Laboratory. In 1986, it was used for the first time as a software package. After that, however, it became pretty famous for Matrix computations. Therefore, it went through a lot of developments and became an ideal choice to perform various functions, such as statistical analysis, optimisation, and plotting, just to name a few.

  1. SQL 

You need to learn this skill to handle relational databases. As a general rule, SQL databases have a different structure than that of NoSQL ones. For example, if you are using SQL for data storage, you will use tables. On the other hand, you may have to use graphs or documents to store data in different database management software.

  1. Interdisciplinary 

Data science is called an interdisciplinary field. In other words, you need to get information from various sources, such as mathematics, computer science, statistics, and machine learning, just to name a few. Moreover, it is essential to keep in mind that you need help to learn the skills. 

You need a wide range of skills to become a professional data scientist. For example, you need to learn programming languages such as SQL, R and Python. Apart from this, you have to have a strong knowledge of statistics as you will have to use Complex algorithms to analyse large-scale data. 

  1. Collaborative

You may have to work with professionals from other fields if you are a data scientist. In other words, working in the in the field of data science requires teamwork. Therefore, you need to collaborate with data analysts, executives, software engineers, and other professionals.

Apart from this, in some projects, you may need to find out if they are complete or need more work. There is in that there is always a possibility of further analysis. In other words, there could be multiple interpretations of a question. 

  1. Creativity 

Another ability required for data science is called creativity. In other words, you should be able to find creative solutions to problems. And we know that most people cannot think outside the box and just follow the trends. So this is another reason why most people find data science quite challenging.

  1. Communication skills 

Since this field has a lot of competition, you may need help to make room for yourself. Therefore, you need to find a way to land a job and prove yourself valuable to the organisation you are working for.
