Best Online Courses on Data Science for 2022

Data science continues to evolve as one of the most promising and in-demand career paths for skilled professionals. Today, successful data professionals understand that they must advance past the traditional skills of analyzing large amounts of data, data mining, and programming skills. In order to uncover useful intelligence for their organizations, data scientists must master the full spectrum of the data science life cycle and possess a level of flexibility and understanding to maximize returns at each phase of the process. Let’s find out the best online courses on data science.

Why Data Science?

Data science or data-driven science enables better decision-making, predictive analysis, and pattern discovery. It lets you:

  • Find the leading cause of a problem by asking the right questions
  • Perform exploratory study on the data
  • Model the data using various algorithms 
  • Communicate and visualize the results via graphs, dashboards, etc.

Will Data Science be in Demand in 2022?

In 2020, every person generated 1.7 megabytes of data in just a second. Internet users generate about 2.5 quintillion bytes of data each day. Data is being used to create massive change in many industries — healthcare, finance, marketing, business, etc.

However, data science in practice is very different from data science in theory. There are skills that will set you apart from the average data science aspirant.

When working in the industry, it doesn’t matter if you work an entire day to make your model 1% more accurate than before. These things might be important in a Kaggle competition, but they don’t matter to stakeholders.

What’s actually happening is that Data Engineering is replacing Data Science!

In the past, these organizations placed too much value on data scientists. They hired data scientists to build profitable models when they didn’t have a proper data pipeline in place.

Data scientists specialize in model building and are unable to do much with massive amounts of real-time, unstructured data flowing in. This meant that they were unable to add much value to the organization — since the data wasn’t prepared in a way that they required it to be.

Now that companies are starting to realize this, they are putting more emphasis on hiring data engineers. Read the following articles for a more in-depth understanding-

What Does a Data Scientist Do?

A data scientist analyzes business data to extract meaningful insights. In other words, a data scientist solves business problems through a series of steps, including:

  • Ask the right questions to understand the problem
  • Gather data from multiple sources—enterprise data, public data, etc
  • Process raw data and convert it into a format suitable for analysis
  • Feed the data into the analytic system—ML algorithm or a statistical model
  • Prepare the results and insights to share with the appropriate stakeholders

If you are planning to start your career in Data Science and wish to know the skills related to it, now is the right time to dive in. Some popular websites offering the best Data Science courses around the web are listed down below.

Data Science Specialization

4.5 (37,544 ratings) || 445,639 students enrolled

This Specialization covers the concepts and tools you’ll need throughout the entire data science pipeline, from asking the right kinds of questions to making inferences and publishing results. In the final Capstone Project, you’ll apply the skills learned by building a data product using real-world data. At completion, students will have a portfolio demonstrating their mastery of the material.

Machine Learning

4.9 (161,517 ratings) || 4,259,647 students enrolled

This course provides a broad introduction to machine learning, data mining, and statistical pattern recognition.

Topics include:

  • (i) Supervised learning (parametric/non-parametric algorithms, support vector machines, kernels, neural networks).
  • (ii) Unsupervised learning (clustering, dimensionality reduction, recommender systems, deep learning).
  • (iii) Best practices in machine learning (bias/variance theory; innovation process in machine learning and AI).

The course will also draw from numerous case studies and applications so that you’ll also learn how to apply learning algorithms to building smart robots (perception, control), text understanding (web search, anti-spam), computer vision, medical informatics, audio, database mining, and other areas.
