What are the skills of a Data Scientist? Is Data Science a field of study? What about data science employment opportunities? How to deal with data and its scientific analysis for a better business prospect.

These are some of the common questions asked on various knowledge sharing online sites like Quora. This blog is going to deep dive into these questions and will present a detailed analysis of the same. In addition, we are going to give you a complete roadmap on how to become a data scientist? But before that you need to know what data science is.

What is Data Science?

Data science is a field of study wherein data is analyzed using some specific parameters and decision is taken based on the pattern and results that are generated after the analysis. It is an interdisciplinary science that involves using scientific methods, algorithms and processes to study the available data and gain knowledge. 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 for analyzing data. The results of the analysis are used by organizations to make smarter  business decisions. In general, a data scientist needs to know how to code so that they can write scripts used to process the data. 

The profession of data scientists has been seeing a rising curve year-on-year. Data science jobs were equally popular in 2020 and continue to be so till now. 

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

The demand for data scientists has paved the way for tools that are graphical user interface based and do not need expert coding knowledge. If you have strong knowledge of algorithms, you can easily build data processing models. However, even if you don't have strong coding knowledge and a special degree in data science, you can still become a data scientist. With good learning capability, you can be a data scientist without a degree in it.

There are online courses on data science like Crampete Data Science Course that gives you a certificate of completion which you can use to get a job as a data scientist. If you prefer attending classes on the schedule, then you can look up online courses for data science at Crampete.

7 steps to become a Data Scientist

So coming back to the 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 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 act as a learning path and will aid an individual in becoming a successful data scientist.

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 remain in the competition, you need to have the following skills.

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 allow 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, and SQL are some of the languages you should consider learning.

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 know a programming language. Tools are available 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. 

Understanding 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.

Machine Learning 

ML is a must for companies whose products are 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.

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.

Data Wrangling

A Data Scientist’s 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 a 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.

Data visualization

Data visualization is important for presenting the inference to laymen for them to easily understand the result.  As a data scientist, you should be able to communicate effectively about your findings, recommendations, and the plan of action.
