What Is Data Science? A Beginners Guide To Data Scientists

What is Data Science?

Data Science is all about opening up the outcomes from any kind of data analysis. Studying, analyzing and simplifying the findings from the same is a critical task. Hence, it requires special skill sets to be a data scientist. You should have the capability of studying everything at a molecular and granular level for making accurate decisions. Becoming Data Scientist is a dream for many but does not have the end to end knowledge about the same. So, today we will discuss following points to let you know everything about data science and data scientists.

• What is a Data Scientist?
• What are their roles & responsibilities?
• Top 5 skills required to become a Data Scientist

Data scientists play a huge role in developing data which involves building various algorithms, testing, technical deployment and many more.

What is a Data Scientist?

Data Scientists can be considered as a whole new breed of experts who are proficient in analyzing the critical most data, be it technical data or any other complex data. They come with a common quality in all of them, i.e. to dive and explore every problem for which the solution is to be found. They are always curious to explore.

They can be an IT professional, computer scientist, mathematician or any other professional because they should be always ready to jumble between different industries.

Data Scientists Roles & Job Responsibilities

It is not everyone’s cup of tea and therefore requires an array of skill sets as well as tools that every data scientist must master before entering into his/her actual role. Take a glance at what a data scientist has to do to fulfill his responsibilities at the best.

• Collect data from all possible sources. From internal database encoded in SQL or from web APIs.
• Know to carry out the exploratory data analysis so that you can navigate between various dataset and find out appropriate conclusions based on entire research.
• Organizing huge datasets to get appropriate and useful insights.
• Programming as well as dealing with algorithms using a large number of datasets should be on the fingertip and an easy-to-go matter.
• Converting jumbled data into meaningful data so that it is easy to understand for others that will be helpful to communicate easily about all findings and simultaneously use them for a greater business growth.

The demand for Data Scientists was not that high in the last decade, but as we are living in the age of Big Data, the demand has been increased in a revolutionary way. We have more data saved in the cloud than ever; therefore we need more people to deal with it. So, overall Data Scientist has impeccable capability to understand, explore and identify

Skills Required To Become A Data Scientist

1). Programming and Statistics

Irrespective of companies that you are going for an interview, you should have sufficient knowledge of programming languages like R, Python, etc., and language for database querying i.e. SQL.

When it comes to an understanding of statistics, a data scientist should be known to distributions, statistical tests and many more. Data-Driven companies value this quality more than any other companies because there, stakeholders rely on decision-makers based on various experiments.

2). Visualizing and Communication of data effectively

Both of them are equally important and hence you should have a proper balanced knowledge of both visualizing and communicating. Just for an example, Tableau is a great one to look for. It is a very popular data visualization and dash-boarding tool that is being widely used. It is essential for us to not being just familiar with the tools used for visualizing data, but also to understand the basic principles behind these visually encoding data and communication information.

3). Machine Learning

If you’re going to target a company that already deals with a huge amounts of data, like Netflix, Google Maps, etc, you may give special attention towards increasing your knowledge about machine learning methods. What I mean to say that you need to put more focus towards ensemble methods, k-nearest neighbors, random forests, and more. More important for you is to understand the wide strokes and understand when it is the right time to use different techniques for different aim. 

4). Software Engineering Background

You must be aware that being a data scientist you need to deal with plenty of data logging issues, need to study analyze, segregate, etc. as a part of your job. You should be capable enough to deal with the development of data-driven products. Hence, every company will want a candidate with a software engineering background.

5). Data Intuition

Companies will definitely want a candidate who is an excellent problem solver and also a data-driven problem solver. Yeah, that’s right. Being only an efficient problem solver is not sufficient; you should be impeccable in dealing with data-driven products. At some point in time during the interview process, you may have to face high-level question to judge your problem-solving skills. Just make sure you have these skills before you even apply for Data Scientist.
