Beginner-level course to help you understand key statistical metrics in data analysis.
We live in a world of data. We measure everything from the current temperature to how many steps we take each day. Understanding statistics allows us to analyze and interpret numerical data.
There are two branches of statistics. Purely mathematical statistics, or statistical inference, is about drawing scientific conclusions from data. Descriptive statistics deals with the collection, analysis, presentation, and summarization of data. This introductory course explains the basic concepts of descriptive statistics. It's a must for anyone who works with data.
During this course, you will learn about the three common measures of central tendency: arithmetic mean, median, mode. You'll also learn how to measure the variability of a distribution and compute variance and standard deviation. You'll get to know how to measure asymmetry and you'll be able to define fancy words like "kurtosis" and "skewness". And you'll acquire some basic data visualization skills, too: how to create and read histograms, bar charts, and box plots.
Don't worry if you're completely new to statistics: we've designed this course for absolute beginners. All you need is some basic math skills and an Internet connection.
