Data science is the most happening in
the current world, Data is everywhere and no work is done without data. What
brand do you prefer to wear is data and that data is important for all the
clothing brands to enhance themselves. Which is also known as Data analytics,
analytics of data is a huge hit because every firm wants to know "what is
consumed? what to be enhanced? what will be liked? etc" to enhance its
performance. Let me get a bit practical, the scope for data science is huge and
bright, also in terms of employment data scientists are highly valued and the
pay scale is really good. But, what requires to be one? Technical skills,
strong strategic skills. Ability to convert the numerical and effectively tell
the organization that you work for, where and when do they need to concentrate.
Let me put this in a simple way, you need to be an amalgamation of statistics,
programming, and design. In this article let me concentrate on courses that one
can take up for " Data science and data visualization".

There are Three Main Courses for you to
learn which will build a great profile and attract recruiters to choose you,
and guess what some of the courses are free and you also get certified 

R Programming 

&nbsp;R in data science is mainly used
in data analysis. Everything is data and not just academically it helps you to
boost your profile, there are many firms that use this programming. Uber,
Google, Airbnb, Facebook, etc... they use this programming.

What exactly is R programming used for?

<ul>
 <li>Statistical
 inference</li>
</ul>

<ul>
 <li>Data
 analysis</li>
 <li>Machine
 learning algorithm</li>
</ul>

Machine Learning is what is booming
right now and if you are looking to excel in it then, R is good to go.

List of company names that&nbsp;use R
Programming:

Google uses R in many ways. They use R
to make online advertising more effective.

Facebook uses&nbsp; R for many purposes
and one main purpose is to analyze user behavior.

What are you waiting for? If you are a
programmer kind of person and looking to excel in data science "R
programming" is the best choice.

Twitter, Airbnb, IBM, Microsoft,
etcetera.

&nbsp;PYTHON

&nbsp;Python is closely associated with
machine learning, imagine a day without asking Siri to look after your
reminders, and not to ask Alexa about what's happening? These AI (Artificial
Intelligence) are ruling over the world. It's not just Google, Amazon and
Apple, but there are a lot of automobile firms who want automation and online
streamers who require bots.

As a Python programmer, you are just
making the AI work without being explicitly programmed.

Python is known for its simplicity and
if you are looking for a course that is effective and easy " Python "
is good to go.

buying patterns and gives you accurate recommendations. (Python is used)

Spotify (Back end), Netflix, Uber,
Dropbox, Pinterest, etcetera.

&nbsp;TABLEAU

&nbsp;Let us say, you are that person
who is not that into programming but data interests you. Let's get you into the
reporting side of the data. Imagine you as a data analyst who can generate
reports which will give more than what an excel sheet could. Bring all the data
and submit it as an excel sheet, boring? Let's make data visualization
effective with this amazing software "TABLEAU" Let's turn normal data
into insights with this software. It is also one of the fastest emerging
business intelligence tools.

&nbsp;

<ul>
