A Data Scientist is a professional who arrives at business conclusions using advanced level data techniques. They are responsible for data prepossessing, interpreting data, building machine learning models, and building data visualizations.

Data Scientist Role and Responsibilities

The main job of the data scientist is to work closely with the business stakeholders to understand their organizational goals and determine how data can be used to achieve those goals.

  • A data scientist performs multiple tasks and works in a team.
  • There are several tasks performed by data scientists.
  • They manage all the data and ensure the best result will be achieved from the raw data.
  • They help business owners to make informed business decisions.
  • They develop the models to identify the latest trend in the market.
  • They achieved the reports from the collected data.
  • Understanding the business problem and converting it into an analytical problem
  • Identify the right data sources to solve the problem.
  • Extract the data from data sources that are identified
  • Prepare the data set for analysis. 
  • Check if there are missing values and take a call on how to deal with them.
  • Check if the data is in the proper format or else re-format the same.
  • Identify the evaluation metric for the problem.
  • Coming up with proper validation methodology
