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 operations, Expressions and variables

Tuple, List, Dictionaries and set.

Conditioning and branching( if, if-else, if-elif-else)

Loops(for, while)

Functions

Object and classes

File operations

Libraries - Pandas , Numpy, matplotlib and sklearn.

DATA ANALYSIS AND MACHINE LEARNING -

Importing and exporting of data.

Identifying and dealing with missing values.

Data normalization

Binning

Co - relation

Linear regression with single and multiple variables(prediction).

R - Squared and Mean Squared error. 

Model Evaluation parameters. 

Supervised and unsupervised learning. 

Classification and algorithms( SVM, Logistics regression, Decision tree, K- nearest neighbours ) 

Clustering( k mean cluster, hierarchical cluster, and density based clustering).

 

These are the core skills that everyone should need. You can learn all skills on internet ( YOUTUBE IS THE BEST SOURCE) if any one want to go for paid courses. IBM DATA SCIENCE is one of the best.

There are more skills like MS - EXCEL , handling with database queries, story telling and presentation skills.

VIRTUAL DATA SCIENCE INTERNSHIPS -

KPMG DATA ANALYTICS INTERNSHIP

QUANTIUM DATA ANALYTICS

DATA@ANZ 

 

I try to covered many resources and skillset that are required for an entry level Data Science / Data Analyst profile.

If anyone has query regarding post, do comments.
