Which Skills are Required for Data Scientist


Data science is an extensive term that includes data analytics, Artificial Intelligence, data mining, machine learning, Deep Learning, and several other interrelated fields. Data Science is certainly one of the fastest-growing fields in sense of both career opportunities and salary. In the field of data science, you get to learn a lot of things in a short period of time. Data scientists need to be proficient in a variety of computer languages and statistical computations. Also, it requires good interpersonal as well as communication skills. Data Science Training in Gurgaon can help you start your career in this domain. Certainly, this is a great career choice. As it will always host a plethora of job opportunities for all individuals.

Who is a Data Scientist?

Basically, a Data Scientist is responsible for collecting and analyzing huge, structured, or unstructured data sets. This profession makes use of math, statistics, and computer science skills to understand large amounts of data. Further, they apply the information to create commercial solutions to the problems coming to the organization.

For creating a descriptive report of data for creating solutions, they follow the process of collecting, process, modeling, and evaluating data on the basis of industry trends. Additionally, they even ensure that the data is properly cleaned and ready to use in the near future. Data scientists are analytic professionals that use their knowledge of technology to look for patterns and handle data. Further, they bring out solutions to solve difficulties with some useful data and not on some assumptions. A data scientist is responsible for cleaning data and adequate storage. Today, in the data-driven world, they are in high demand and experience good job growth. 

Essential Skills for a Data Scientist

1. Fundamentals of Data Science

  • Figuring out the difference between deep learning and machine learning?
  • A deep understanding of different fields of Data science, data engineering, and business analytics, and the differences between them.
  • Commonly used tools and terminologies.

2. Deep understanding of mathematical concepts of statistics and probability


When creating high-quality models, you need a thorough understanding of statistics. Machine Learning starts with statistics and further continues to evolve.

Indeed, statistical knowledge is a must in the profession of data scientists. It is important to clearly understand the process of descriptive statistics like mean, median, mode, variance, and standard deviation. Data Science Training in Delhi can help you prepare with all these basics.

3. Knowledge of Programming Languages

Data scientists need to be an expert in advanced statistical modeling tools with an understanding of programming. These come in addition to having a deep understanding of mathematics and statistics. Here is a list of programming languages that are preferred for the role of a data scientist.

Python: Python is a useful language for handling the scenarios of data mining to developing websites to running embedded systems with a single language. Pandas is a Python data analysis package that allows you to do everything from importing data from Excel spreadsheets to plotting data with graphs or tables.

R Programming: R is a software package that offers functions for data manipulation, calculation, and also graphical display. However, R is widely in use in academic environments. Implementation of Machine learning algorithms may be faster and easier. Data Science Training in Delhi can help you cover the topics of statistical and graphical representation, linear and non-linear modeling, time-series analysis, classification, and clustering.

4. Understand the process of Extracting Data and its Transformation

You may have different data sources, like MySQL, Google Analytics, MongoDB, and more. You must know how to extract data from these sources and further transform it to store it in a suitable format for querying and analysis. Lastly, you need to load the data into the Data Warehouse which is useful for analyzing it. 

5. Understanding of Data Wrangling and Data Exploration:

Data Wrangling is the cleaning of complex data collections for easy access and further analysis. 

The starting phase in your data analysis starts with the process of exploratory data analysis (EDA). Now, here you analyze the type of data you have as well as what questions you want to ask and how, as well as how to modify your data sources to get the answers to the problem. All this is done by identifying the patterns, trends, unexpected outcomes, outliers, and more. With Data Science Training in Gurgaon, you can learn the process of data manipulation and wrangling to make better data-driven judgments. 

6. Knowledge of Data Visualization

Data visualization is a critical approach for conveying information in an understandable format. Data Visualization becomes the most important skill for effectively connecting with end-users. A Data Visualization professional understands how to make use of graphics to convey a message. Initially, you need to be comfortable with making histograms, bar charts, and pie charts. And further move to advanced charts like waterfall charts, thermometer charts, and more. 

7. Comprehensive Knowledge of Machine Learning

Machine learning is certainly a must-have skill for any data scientist. Predictive models are built using machine learning. You can start with simple linear and logistic regression models and then move to sophisticated ensemble models like Random Forest, CatBoost, XGBoost, and others. An understanding of this algorithm is useful, however, knowing how they operate is even more necessary. 

8. Good Communication Skills

Data only has meaning after correct manipulation. A good Data Scientist needs to effectively communicate. Communication can make a lot of difference in the outcome of a project. In most data scientist professions, great communication skills are a must. You require to have a firm grasp of business needs to clearly communicate the data.  


The field of Data science is growing at such a rapid pace that mastering any single one is pointless. You moreover need to have a set of multiple skills to thrive in this field. Start your journey with Data Science Training in Delhi and take benefit of opportunities coming to your hand. Also, being a data scientist in this era is exciting. There are a plethora of opportunities in this field and offers a very promising career.
