What is a "measure of spread" and what does it tell us about a data set? Why are scatter plots useful in comparing two variables? How might you go about designing a controlled experiment? If you are interested in exploring (or teaching) answers to these questions, the Crash Course YouTube channel recently launched Crash Course Statistics - a series of short videos dedicated to helping people make sense of statistics in their lives. This series is hosted by Adriane Hill, a journalist for NPR's Marketplace and the cohost of the Crash Course Economics series. Recent episodes of Crash Course Statistics have examined topics including mean, median, and mode; data visualizations, and how surveys can be biased. New episodes of Crash Course Statistics are released weekly, so stay tuned. As of this writing, the series contains ten episodes.
