Skills for a Data Scientist

Probability & Statistics

Data Science is about using capital processes, algorithms, or systems to extract knowledge, insights, and make informed decisions from data. In that case, making inferences, estimating, or predicting form an important part of Data Science

Programming, Packages and Softwares

Of course! Data Science essentially is about programming. Programming Skills for Data Science brings together all the fundamental skills needed to transform raw data into actionable insights. While there is no specific rule about the selection of programming language, Python and R are the most favored ones.



Data Wrangling

Data Wrangling is the process where you prepare your data for further analysis; transforming and mapping raw data from one form to another to prep up the data for insights. For data wrangling, you basically acquire data, combine relevant fields, and then cleanse the data.


Database Management

atabase Management quintessentially consists of a group of programs that can edit, index, and manipulate the database. The DBMS accepts a request made for data from an application and instructs the OS to provide specific required data. In large systems, a DBMS helps users to store and retrieve data at any given point of time.


Data Visualization

It gives me the power to craft a story from data and create a comprehensive presentation. Data Visualization is one of the more essential skills because it is not just about representing the final results, but also understand and learn the data and its vulnerability.

Machine Learning

If you work with a company that manages and operates on vast amounts of data, where the decision-making process is data-centric, it may be the case that a demanded skill is Machine Learning.

Microsoft Excel

We know MS Excel as probably one of the best and most popular tools to work with data. We might be hearing, “Hey, did you receive the Excel boss sent? Wait, aren’t we discussing skills for Data Science? Excel? I always wondered there must be some easy way to manage data
