Lab 8: Correlation, Variance of Sample Means Welcome to Lab 8! In today's lab, we will cover two relatively orthogonal concepts. First, we will investigate the variance of sample means, found in Se ... ction 14.5 (https://www.inferentialthinking.com/chapters/14/5/variability-of-the-samplemean.html) of our textbook. We will also get some hands-on practice with understanding the association between two variables, which you can read more about in Section 15.1 (https://www.inferentialthinking.com/chapters/15/1/correlation.html).

How Faithful is Old Faithful? (Note: clever title comes from here (http://web.pdx.edu/~jfreder/M212/oldfaithful.pdf).) Old Faithful is a geyser in Yellowstone National Park in the central United States. It's famous for erupting on a fairly regular schedule. You can see a video below.
