Data Science Tutorial for Beginners - 1 | What is Data Science? | Data Analytics Tools | Edureka

Data Science is all about extracting knowledge from data. Data Science is the integration of methods from mathematics, probability models, machine learning, computer programming, statistics, data engineering, pattern recognition and learning, visualization, uncertainty modelling, data warehousing, and high performance computing with the goal of extracting meaning from data and creating data products. This interdisciplinary and cross-functional field leads to decisions that move an organization forward in terms of proposed investment, decisions regarding a product or business strategy.

Data Science is a buzzword, often used interchangeably with analytics or big data. At times, Analytics is synonymous with Data Science, but at times it represents something else. A Data Scientist using raw data to build a predictive behaviour model, falls in to the category of analytics.

About the Data Science Course at edureka! -

This Data Science course is designed to provide knowledge and skills to become a successful Data Scientist. The course covers a range of Hadoop, R and Machine Learning Techniques encompassing the complete Data Science study.
Course Objectives

After the completion of the Data science Course at Edureka, you should be able to:

Gain an insight into the 'Roles' played by a Data Scientist.
Analyse Big Data using Hadoop and R.
Understand the Data Analysis Life Cycle.
Use tools such as 'Sqoop' and 'Flume' for acquiring data in Hadoop Cluster.
Acquire data with different file formats like JSON, XML, CSV and Binary.
Learn tools and techniques for sampling and filtering data, and data transformation.
Understand techniques of Natural Language Processing and Text Analysis.
Statistically analyse and explore data using R.
Create predictive using Hadoop Mappers and Reducers.
Understand various Machine Learning Techniques and their implementation these using Apache Mahout.
Gain insight into the visualisation and optimisation of data.

Who should go for this course?

This course is designed for all those who want to learn machine learning techniques and wish to apply these techniques on Big Data. The course is amalgamation of two powerful open source tools: 'R' language and Hadoop software framework.

You will learn how to explore data quantitatively using tools like Sqoop and Flume, write Hadoop MapReduce Jobs, perform Text Analysis and implement Language Processing, learn Machine Learning techniques using Mahout, and optimize and visualize the results using programming language 'R' and Apache Mahout.

This course is for you if you are:

A SAS, SPSS Analytics Professional.
A Hadoop Professional working on Database management and streaming of Big Data.
An 'R' professional who wants to apply Statistical techniques on Big Data.
A Statistician who wants to understand Data Science methodologies to implement the statistics methods and techniques on Big data.
Any Business Analyst who is working on creating reports and dashboards.

Pre-requisites

Some of the prerequisites for learning Data Science are familiarity with Hadoop, Machine Learning and knowledge of R (recommended not mandatory as these concepts will also be covered during the course). Also, having a statistical background will be an added advantage.
Why Learn Data Science?
'Data Science' is a term which came into popularity in past decade. Data Science is the process of extracting valuable insights from "data". It is the right time to learn Data science because:

We are living in the Big Data Era, Data Science is becoming a very promising field to harness and process huge volumes of data generated from various sources.

A data scientist has a dual role -- that of an "Analyst" as well as that of an "Artist"! Data scientists are very curious, who love large amount of data, and more than that, they love to play with such huge data to reach important inferences and spot trends. You could be one of them!

As 'Data Science' is an emerging field, there is a plethora of opportunities available world across. Just browse through any of the job portals; you will be taken aback by the number of job openings available for Data scientists in different industries, whether it is IT or healthcare, Retail or Government offices or Academics, Life Sciences, Oceanography, etc.

Thanks for explaining from the beginning... Its very useful and easy to understand...

[shantanusankpal]

Sir I am an Instrumentation Engineer and have no knowledge of programming. But I am interested in data science and willing to learn. How should I start my carrier in this field as I have no prior experience in this field?

[VishalSanghi]

Very long time I was searching for this....this video has connected most of the links that were disconnected in my mind....thanks a lot for sharing

[mukeshbhatt]

great insights in data science technologies

[narendraprasadkarumanchi]

I am planing to learn the Data science, I am not very good in maths and programming language (i.e C, C++ and Java ) as you said java is used in hadoop,
But I have good experience in SQL/PL SQL and MS office.

Please suggest Shall i Join Data Science?...

[AshutoshKumar-hwgu]

very useful but i just want to ask one thing i am not very good in maths and programming language as you said java is used in hadoop so how difficult it will be to become a data analyst or data scientist for me .Reply Plz

[TheQuitesensible]

Hi Edureka,

I am new into Data Science using R. I have learnt few initial things of R.But i m getting confused what all Linear Algebra and Statistics concepts are required to learn for beginners. Because Linear Algebra and Statistics are vast topics.

Can you suggest some concepts of Linear Algebra and Statistics for beginners?

[priyalambani]

Hi, I am B.Com student and after that i had done Diploma in Computer Applications and then certification in Big Data Hadoop from a local institute. So I am thinking to go for data science course but I am confused whether to do or not because I don't have any work experience. So I hope that you will help me in this case and clear my confusion.

[polesetti]

Excellent playlist, thanks for sharing.

[preetyk]

hi sir, your tutorial is very good, i want to know if i will cover these playlist will it be sufficient enough to get a good knowledge and say that i know data sciene

[wasi-wasif]

Sir I am a web designer and i want to move to this field i have good knowledge about mysql and its queries, so what should i know. and what are the proramming languages used in data scientist.

[aqirana]

Hi, I am totally new to this. One of my friend said I need to learn R language as it gives you a good pay package and you will learn a lot, but right now I am little bit confused, from where do i start, what are necessary steps to learn R language, like first i need to understand Data Science Course or what. kindly help me out. Your help is highly appreciated. Moreover i am a computer engineering graduate so i know coding a little bit.

[ebzdimpu]

Great job guys. Btw I am a mechanical engineer by education. have work exp for about 6 years mostly in marketing, BD, sales. Have also worked in the production field. Right now doing my pgpm exe while working. But i am interested in big data, data science etc. I have no knowledge of any programming language what would you suggest? what should i learn if i sill want to stay in the marketing side

[LearnNGrowMind]

Hi Sir i want to know that i am currently working a research Associate its like data pull or data analysis so i want to know my experience will count in data scientist field or not and also want to know how much scope for data science in India.

[ALOK]

I have no knowledge of programming language, suggest me the very basic way to start with Data Science

[BeHappy]

Hai this is Nagaraju, B.sc, am interested to learn data science, but I'm new to this. please help me how this course will be, and am poor in c, java

[vishals]

I am very much familiar with SAS, so instead of R or Hadoop can I learn data science

[aditijain]

Hii... This is Aditi Jain and doing PhD from finance... And want to learn data science from starting... How can I learn... Please help me
