💻 Which Data Science Course Provider is best for me?
- Udemy and Eduonix are best for practical, low cost and high quality Data Science courses.
- Coursera, Udacity and EdX are the best providers for a Data Science certificate, as many come from top Ivy League Universities.
- YouTube is best for free Data Science crash courses.
- PluralSight, SkillShare and LinkedIn are the best monthly subscription platforms if you want to take multiple Data Science courses.
- Independent Providers for Data Science courses & certificates are generally hit or miss.
💼 What is Data Science used for?
Big data. Virtually every organization has it and most want to find ways to use it to help them grow their business. That's where data scientists come in. Data scientists know how to use their skills in math, statistics, programming, and other related subjects to organize large data sets.
📃 Is a Data Science Certificate worth it?
Yes and No. Certified Data Science developers on average make more money. Having a Data Science certificate greatly increases the chance of landing an interview and can open otherwise closed doors. Coursera, Udacity and EdX offer excellent certificate options for impressing your future employers. Eduonix, Udemy and several other providers offer certificates, but they aren't as reputable. If you have a Computer Science Degree, certificates are not as important. Still, many employers won't care about certificates, but rather your interview skills, experience and/or skills assessment.

The Data Scientist's Toolbox (2019)
5.0
This Coursera course was created by Johns Hopkins University. It introduces tools and resources that are essential to working in data science, and it splits lessons into a theoretical and practical half.
Pros
Cons
-
- Course takes a light introduction on a broad range of topics that all apply to data science. Great preparation for a full-dive, multicourse adventure into data science.
- Covers mindset of data science in a way most courses skip.
- Course ensures that you have the tools to take on a journey to truly master data science.
-
- Course covers a substantial range of data science tools. Accessing all of them can potentially add a hefty price tag to completing the course.
- Course is not a Capstone project. It is intended to prepare for a data science Capstone project.
- Course teaches very little data science itself. It is more like going over the syllabus and prerequisites before diving into real learning.

Learn Python For Data Science (2016)
4.6
This YouTube course by DataCamp is a 40-part video series that explains how to use Python in data science. While it serves as an introduction to data science applications of Python, it is not an introductory coding class. The free YouTube series can be supplemented by a paid course run through DataCamp.
Pros
Cons
-
- YouTube tutorials are always free and repeatable - one of their greatest strengths.
- Course delves well beyond the basics of Python and gets deep into databases for data science.
- Course caters to an audience that already understands the fundamentals of programming and doesn't waste time on things you already know.
-
- Content covers the usage of powerful resources. Accessing and installing them can provide barriers in completing the course.
- Interaction with instructor is extremely limited unless you pay for the additional DataCamp course.

-
- It's short. Truly living up to the word "intro", this course does not delve deeply into analytical techniques. It only covers the bare basics and will not teach the tools for professional analysis.
- Tutorial is more fun than serious. While information is accurate, it does not reflect the data science profession.
- Series is more of an overview of a few ideas than a true course in data science.
