Let’s look at each vertical and related resource to get started.

Programming Language

It is very important to master a programming language related to data science. Following are the recommended resources to get started.

  1. Introduction to Python (Datacamp)
  2. Grokking Data Science (educative.io)
  3. Complete Python Bootcamp (Udemy)
  4. Python for Data Analysts (Pluralsight)
  5. Introduction to R (Datacamp)
  6. Getting Started With R (Edx)

Data Analysis

Data analysis is a very important vertical in data science. it helps in finding meaningful data by analyzing multiple sources of data. The data source and type of data could be different from org to org. Normally data collection happens through multiple sources to form a data lake.

There are many data management strategies used based on data classification.

Following are the recommended tracks to get started with data analysis.

  1. Data Analyst with Python (Datacamp)
  2. Introduction to Data Analytics for Business (Coursera)
  3. Data, Analytics and Learning (Edx)
  4. Intro to Data Analysis (Udacity)
  5. Data Analytics Using Python (Futurelearn)

Data Visualisation

Data visualization transforms massive amounts of processed data into meaningful visuals for the key stakeholders in the business. A business analyst can make use of this useful information to find opportunities for business growth.

Following are the good resources to get started with data visualization.

  1. Data Visualization with Python (Datacamp)
  2. Data Visualization: A Practical Approach for Absolute Beginners (Edx)
  3. Learning Python for Data Analysis and Visualization (Udemy)
  4. Data Visualization Nano degree (Udacity)

Machine Learning

For all predictive analyses, machine learning is the key part. ML deals with data Classification, Regression, reinforcement learning, Deep learning, Dimensionality Reduction, Clustering, etc.

Get started with the following recommended machine learning resources.

  1. An Introductory Guide to Data Science and Machine Learning
  2. Machine Learning A-Z™: Hands-On Python & R In Data Science (Udemy)
