Whether you're looking at scientific data or stock price charts, box-and-whisker plots can illuminate patterns in your life. This tutorial covers what they are, how to read them, and how to construct them.
Mean absolute deviation (MAD) is a tool for reasoning about the spread of data, just like interquartile range (IQR). Higher values of MAD tell you the data is more spread out. Lower values of MAD tell you the data is closer together.
Like people, no two data distributions look exactly the same. Well, maybe that's not always true... Anyway, the point is that each data distribution has it's own shape. In this tutorial, you'll learn new vocabulary that will have you discussing the shape of data distributions like a pro in no time!
