Fundamentals of data science and being a data scientist
Data science is not a single field. It is a combination of different disciplines. A data scientist has to have a strong background in mathematics and statistics. One must also possess an understanding of algorithms like machine learning and software algorithms as a data scientist.
A data scientist should also gain some level of coding but not as much as a software engineer. However, some companies may require a data scientist to have a decent level of coding to solve easy to medium coding problems.
Furthermore, a data scientist should know data structures and data visualization. A good data scientist also knows how to communicate data, that is, explaining to non-technical people what he or she has done with the data.
A data scientist may not have all of these skills at once. This is to give an idea of how broad the area is when we talk about a data scientist. It also has common areas with data analysts and data engineers, which are slightly different from data scientists.
In sum, we can say that a data scientist should have some data engineering knowledge and data visualization skills, plus machine learning and business context. Being familiar with business is the most exciting part of being a data scientist.
A data scientist works in different domains. For example, a data scientist might work for a retailer or solve a problem for a healthcare provider or a manufacturer. These are all different domains where a data scientist needs to have business context. You cannot be a good data scientist without having a business understanding. Because data is just a bunch of numbers, and those numbers are meaningful when interpreted within the business context.
Why do companies need data scientists?
In today’s data-driven world, businesses collect a huge amount of data from various resources, such as their websites, social media accounts, customer calls, etc. They have to process and analyze this vast amount of data to extract valuable insight. Consequently, data science is now one of the most desirable professions in the business world.
The Harvard Business Review even labeled it the sexiest career of the twenty-first century. This isn’t a surprise, as big companies like Google, Facebook, IBM, and Amazon have all invested heavily in data science to improve their products and enhance customer service. This has opened up additional opportunities for data scientists.
To turn companies’ great amount of data into actionable insights, data scientists employ several techniques. Data scientists combine their business understanding, problem-solving, programming, and data visualization skills to help businesses evaluate their data. Companies want to use the data they have to derive actionable insights, thereby making informed decisions about customer behavior, product performance,etc.
We can say that a data scientist directly affects a business with information gleaned from data. So, the demand for data scientists has increased significantly and this trend will continue in the future.
