Skillset, topics, projects and virtual internships for DS

This post is for those who are beginner and do not have any idea about topics that they need as a beginner DATA SCIENCE/ DATA ANALYST.  I am also facing the same problem before a year ago and till date I have some relevant knowledge about data science and also have some projects.  People are saying the we need so many skills like Mathematics, Programming language, some cloud concepts too. Actually they are right. Being a Data Scientist is not like being a web developer or a front-end developer that have limited skill set.  In this post I will tell you the exact topics that you need to learn at beginner level. MATHEMATICS Descriptive Statistics, distributions, hypothesis testing and regression analysis. Bayesian Thinking, conditional probability, priors, maximum likely hood. Vectors and matrices Matrices operations Eigenvalues and eigenvectors Linear and non linear functions Multivariable calculus  PROGRAMMING LANGUAGE(Python or R)    Data types, String oper...

 Data Scientist

In a nutshell, Data Scientist is the person having statistical knowledge with some coding skills.
Data Scientist are those who analyze the previous  records and fetch out the future insights. And that is the difference between Data Scientist and Data Analyst. 

Analyst are those who tells about past insights of data and data Scientist are those, who can tell about the future related with those insights.

Let's take an simple example, suppose we have a some records of person salary related to their yearly experience. By having records, we can perform number of operations. Analysts can tell about the annually growth in salary, can give the different different visualization with clarity. 
What will happen if we will want to predict the salary of new employees who was not working with company previously, here the role of Data Scientist comes as he is going to tell about the future insights.

Big tech companies like amazon or google , they all are doing their daily activities oj the basis of data they stored in their Information system.
And these work are done by the Data Scientist/ Data Analyst and Machine learning engineers. 

Scope

Data is everywhere so scope of data Scientist in every fields like medical, information technology, finance and so on..

"According to Linked In Data Scientist job is the highest paying job from 2019."

Skills

If we talk about skills, there will not be any end  As much you can get, will good for you. But some of important skills that Data Scientist should have are listed below.

1. Programming skills 
2. Statistical knowledge 
3. Multivariable calculus 
4. Linear algebra
5. Knowledge of Data bases and cloud based architecture 
6. Ms Excel

If person from non mathematical background are wanted to be Data Scientist, things will be quite challenging for them. 
But programming languages like python, R are number of libraries that makes things quite easier.

Thank you for reading this post.
