Who is a Data Scientist?

A Data scientist is one who estimates unknown data by writing complex algorithms and building statistical models. He is responsible for interpreting large amounts of data and carrying out analysis to find trends and gain more in-depth insights. 

Data scientists aid companies in addressing afflicting challenges by extrapolating and sharing such useful insights. They use a mixture of computer science, simulation, statistics, analytics, and math skills, as well as sound business judgment, to find answers to major questions that assist companies in making objective decisions.

Roles and Responsibilities of a Data Scientist

If you are planning to become a Data Scientist, then be prepared for deliverables such as Prediction such as predicting a value based on inputs, Classification such as whether it is spam or not, recommendations, pattern detection and grouping, Anomaly or fraud detection, image, video, or text recognition, Produce actionable insights with the help of reports, Visualizations, etc. Apart from this, Data Scientist is also responsible for Automated processes and Decision-making, Segmentation, for instance, demographic-based marketing, Optimization, and Forecasting sales revenues.

In general, he is responsible for asking the right questions to begin the discovery process. Based on that, he acquires data, processes and cleans that data, and integrates and stores the desired data. Also, he is responsible for initial data investigation and exploratory data analysis and choosing potential models and algorithms. Now when models and algorithms are chosen, data scientists apply data science techniques, such as machine learning, statistical modeling, and artificial intelligence, to get the desired results. After this, he is responsible for measuring and improving results, presenting outcomes to stakeholders, and making adjustments based on feedback. And this process, right from discovery to making adjustments, keeps going to solve a new problem. 

But do remember, if you are seeking a career in the data science domain, you must have:

  • Sound knowledge of analytical tools
  • Developing software, data models, and algorithms
  • Experience using web services such as Redshift, S3, Spark, etc. 
  • Programming advanced computing
  • Executing predictive analytics
  • Data Visualization
  • Hands-on experience with Hive or Pig 
  • Proficient in SQL
