This blog is going to deep dive into these questions and will present a detailed analysis of the same. In the process we are going to give you a complete roadmap of how to become a data scientist? But before that we need to know what data science is. .

  • What is Data Science?

  Data science is a field of study where data is analyzed using some specific parameters and a decision is taken based on the pattern and results that are generated by the analysis.  It is an interdisciplinary science that is about using scientific methods, algorithms and processes to study the available data and gain knowledge from it. Crampete Data Science Course shows how to become a Data Scientist from scratch.  

  • Who is a Data Scientist?

 A data scientist is a person who uses a mixture of different concepts from mathematics, statistics, information science and business intelligence to write algorithms to analyze data. The results of the analysis are used to make smarter decisions by industries. In general, a data scientist needs to know how to code so that they can write scripts to run to process the data.   

  • Who can become a Data Scientist? Is it suitable for you?

  While it is a good thing, the demand for data scientists has paved the way for tools that are graphical user interface based and does not need expert coding knowledge. If anyone is strong with algorithms, they can use it to build the data processing models. So, even if you don't have strong coding knowledge and a special degree for data science, you can still become a data scientist. This shows how to become a Data Scientist without a degree but with actionable insight and learning capability.

There are online courses on data science like Crampete Data Science Course that give you a certificate of completion which you can use to get a job as a data scientist.

  • 7 steps to become a Data Scientist

  So coming back to this topic of how to become a data scientist, in accordance with the above discussion, there are a few basic considerations that one needs to fulfil to become a data scientist. You should have an appetite for data. You should have the aptitude to work almost endlessly with the data to produce the best results. Here are the 7 major steps one should take if you are set on becoming a data scientist. These steps will aid an individual on how to become a data scientist in India:

5. A. Skills required to become a data scientist

The list of skills required to become a data scientist is numerous. Here, we will try to discuss a few of them in detail. To become a data scientist or to maintain the edge over the competition, you need to have the following skills.

5. A.1. Programming Language

To become a data scientist, one doesn’t have to be an expert at any programming language as there are a lot of tools available on the internet that allows one to work with data science algorithms. But the knowledge of a programming language sets one apart from others in terms of value addition. It also gives you more room and opportunity to play around with the data and get better (maybe) results. R, Python, Matlab, TensorFlow, Julia, Scala, SQL are some of the languages you should consider learning.

5. A.2. Frameworks and Tools

There are a whole lot of data science tools that make the life of a data scientist easier. Many of the tools that are recently offered in the market do not even need one to become a data scientist to know a programming language. They offer tools for data collection, data analysis, and data visualization. The stack of technology you choose depends upon the industry requirements and purpose of the exercise. There are different tools for collecting data, data analysis, machine learning, and data visualization. 

5. A.3. Understanding of Statistics

Be familiar with advanced statistical concepts. You should have the ability to understand which methods are valid for your case and which are not. Statistics are important everywhere. It is a  must for all data-driven decisions that are made and in cases where you are evaluating experiments.

5. A.4. Machine Learning 

This is a must for the companies whose products are itself data-driven. Even otherwise, it is a great skill to have for a data scientist. Though you can implement quite a few concepts using programming languages like R and Python, you should still learn various basics and algorithms for machine learning.

5. A.5. Linear Algebra and Multivariable Calculus

Linear algebra and multivariable calculus are among the basic mathematics that one needs to hone to become a data scientist.

5. A.6. Data Wrangling

A Data Scientist job is also to learn to work with imperfect data. It comes across as a useful skill to have when there is no organization to data and in companies where the product is not oriented to the data-driven approach. It is also useful in companies which have simply let go of on data and you are an early hire who is there to clean up the mess.

5. A.7. Data visualization

Data visualization is important for presenting the inference to laymen for them to easily understand the result.  As a data scientist one should be able to communicate effectively about your findings, recommendations, and the plan of action. Such visualisation aids in how to become a data scientist in India after science, commerce or any stream of study.
