7 Steps to become a Data Scientist

 What is Data Science?

Data science is a field of study wherein data is analyzed using specific parameters and decisions are taken based on the pattern and results generated after the analysis. It is an interdisciplinary science that involves using scientific methods, algorithms and processes to study the available data.

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 remain in the competition, you must have the following skills.

1.  Learning a 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.

2.  Understanding 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. 

3. Get a Basic 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.

4.  Research about 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.

5.  Learn 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.

6. Get Some Concept on 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.

7. Understand 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 plan of action.
