“I think Dataquest is the best option for learning data skills. I particularly enjoyed the guided projects. They are like the real thing. Dataquest shows you exactly what you need to learn and then helps you apply it.”
In this course, you’ll learn how to summarize distributions using the mean, the median, and the mode — as well as when to use them. You’ll learn which statistic gives you the most information about a distribution so you know not only how to apply them but also why you should.
You’ll then learn to measure variability using variance or standard deviation, and how to locate and compare values using z-scores. We’ll then explore range, mean absolute deviation, variance, and standard deviation. You’ll also learn about z-Scores and how to use them to compare values across any distribution.
Best of all, you’ll learn by doing — you’ll practice and get feedback directly in the browser. At the end of the course, you’ll complete a guided project in which you’ll find the best markets for advertising an e-learning platform that combines your data science programming skills and the statistical skills you’ve learned in this course.
