Course Description

What is data science, why is it so popular, and why did the Harvard Business Review hail it as the “sexiest job of the 21st century”? In this non-technical course, you’ll be introduced to everything you were ever too afraid to ask about this fast-growing and exciting field, without needing to write a single line of code. Through hands-on exercises, you’ll learn about the different data scientist roles, foundational topics like A/B testing, time series analysis, and machine learning, and how data scientists extract knowledge and insights from real-world data. So don’t be put off by the buzzwords. Start learning, gain skills in this hugely in-demand field, and discover why data science is for everyone!

    Data Collection and Storage

    Now that we understand the data science workflow, we'll dive deeper into the first step: data collection and storage. We'll learn about the different data sources you can draw from, what that data looks like, how to store the data once it's collected, and how a data pipeline can automate the process.

    Preparation, Exploration, and Visualization

    Data preparation is fundamental: data scientists spend 80% of their time cleaning and manipulating data, and only 20% of their time actually analyzing it. This chapter will show you how to diagnose problems in your data, deal with missing values and outliers. You will then learn about visualization, another essential tool to both explore your data and convey your findings.

    Experimentation and Prediction

    In this final chapter, we'll discuss experimentation and prediction! Beginning with experiments, we'll cover A/B testing, and move on to time series forecasting where we'll learn about predicting future events. Finally, we'll end with machine learning, looking at supervised learning, and clustering.

    I need to admit that training is very well prepared, all abbreviations are explained so even I was totally noob in this area I would understand all anyway. From my perspective practicing the explained material after each chapter is great to see if I understood what was explained. Thank you!

    Very good class, I'm using it to work with college Professors, as a professor's consultant. The professors that I have been talking with are having a hard time keeping up with all the changes taking place in the AI and Machine Learning fields. So they are looking for outside help and that is where I come in. I would like to talk with someone from DataCamp to help me put together an hour-long presentation to give to college Juniors and Seniors that talks about why students should be looking into Datacamp AI and Machine Learning courses. My email address is [email protected]

    Each lesson was comprehensive and informative. The videos and podcasts were very helpful in understanding the material. I also appreciated the availability of help/hint where I could ask questions and get feedback. After displaying the result, each answer was explained with a few sentences. The XP points kept me going. Overall, this was an amazing course that I would highly recommend!
