Course overview

What You’ll Learn in Probability Fundamentals

As you might have guessed from the title, Probability Fundamentals is designed to give you a working understanding of critical concepts in probability that are relevant to the everyday work of data analysis and data science.

Like all Dataquest courses, you’ll work through this course in your web browser, writing code to apply what you’re learning every step of the way.

Working through the course, you’ll use your Python programming skills and the statistics knowledge you’re learning to estimate empirical and theoretical probabilities. You’ll learn the fundamental rules of probability, and then work to solve increasingly complex probability problems.

Finally, you’ll learn about counting techniques like permutations and combinations before synthesizing all your new knowledge in a guided project building the logic for a mobile app that helps gambling addicts more accurately estimate lottery odds to help them overcome their addiction.

By the end of the course, you’ll understand the difference between theoretical and experimental probability. You’ll have experience calculating the probabilities for a variety of different events, and you’ll be able to calculate the number of permutations and combinations possible in experiment outcomes.

Why Learn Probability and Statistics?

Although a lot of data science work is experienced as programming, almost everything that data scientists do involves working with statistics. When data scientists make predictions, they’re dealing with probabilities. The concept of probability might seem basic, but it’s the foundation for even the most advanced predictive models.

And while the actual mathematical operations are often baked into popular data science libraries for quick application, this convenience can be a double-edged sword. Just because a technique is easy to apply, after all, doesn’t mean that it’s correct to apply in every circumstance.

That’s why learning probability and statistics concepts, including those covered in this course, is so important for data scientists. When you understand the why, it becomes much easier for you to identify the correct statistical technique or calculation for the problem you’re trying to solve.

It also becomes easier to explain your analysis to others when you have a firm grasp of why you used the technique you chose.

“Dataquest starts at the most basic level, so a beginner can understand the concepts. I tried learning to code before, using Codecademy and Coursera. I struggled because I had no background in coding, and I was spending a lot of time Googling. Dataquest helped me actually learn.”

“I liked the interactive environment on Dataquest. The material was clear and well organized. I spent more time practicing then watching videos and it made me want to keep learning.”

“I really love learning on Dataquest. I looked into a couple of other options and I found that they were much too handhold-y and fill in the blank relative to Dataquest’s method. The projects on Dataquest were key to getting my job. I doubled my income!”
