So let us begin by understanding what a data scientist actually does.

What Does a Data Scientist do?

The answer to this question is complex, as data science is not just juggling data and finding solutions. It is a fusion of data, curiosity, creativity, tools, and understanding of the subject.

Becoming a data scientist requires knowledge about the industry and understanding the existing assumptions for clear and better results.

Data science is really useful for a company in its planning stage. It eventually helps in better management of problems, and political analysis, or gives solutions for any social problem or existing predictive models.

Data Scientist Job Responsibilities (Detailed)

  • The data scientist’s work includes collecting, analysing, process, giving a structure and interpreting data for the untrained eyes to make sense of the numbers. They use other sources, such as social media platforms, social chat rooms, etc., to find a better result for the given problem, not restricting themselves to the primary and secondary data sources.
  • They provide solutions for businesses using data-related techniques like statistical distributions and tests. Besides these tools, data scientists also use tools like machine learning, text analytics and deep learning, which includes going beyond and above the primary and secondary data.
  • Data scientists are a bridge between IT and Business/ society. They collaborate and communicate with people from other fields and find the orders and patterns in data. It helps them to see the trends and help with the root cause of the problem or a new policy.
  • They check the parameters and patterns to understand the unstructured data set using algorithms, scientific methods and processes.
  • Other than making sense of the random data, they also participate in creating tools for utilising the data. They may also contribute to the creation of AI tools for the same.
  • Moreover, they organize data storage for future use.

Who Can Be a Data Scientist?

Data scientists are analytical experts who gather and analyze large amounts of data to solve problems or prove a point. They collect large sets of structured or unstructured data based on the subject and use various computer science, math, and statistics tools to interpret data for more comprehensible results.

To become a data scientist, a person must have strong analytical skills and knowledge of math, statistics, and programming languages. If the data in daily life makes sense to someone, they might have what it takes to become a data scientist.

Data Scientist Skillset

  • Typically, it takes a strong interest in math and computer science aided by a curiosity about finding patterns among numbers. An expert data scientist does not stay restricted to conventional sources of information. They usually know where to find the data. It could come from emails, social media posts, etc.
  • They must have good data intuition to understand and find valuable information in any of these sources. While working on the projects, one may not always easily find insights in the given data set.
  • Data scientists must be knowledgeable enough to understand different types of data. This will make them more efficient. They can attend training sessions and boot camps to acquire these data-driven skills.
  • They have to be data-driven and have strong data visualization to become an expert in the job, as, with these skills, they will be able to find the patterns in the data.
  • Some experience in working with large amounts of data is a plus when it comes to becoming a data scientist. Along with this, if they can get some experience in machine learning and statistical modeling, it could prove beneficial.
  • A data scientist must also be a good communicator, as the ideas and patterns found from the complex data need to be disseminated to the organization’s other stakeholders. Strong communication skills will enable them to make the data analysis and predictions interesting and easy to understand for others.
