Day 8 - Causal Relations vs Correlation

Students understood this very well. They struggled at times determining the common variable that affects two other variables. We did the examples together and a few of the questions on page 2 together. The rest they did on their own. They had a bit more practice:

The first sheet of this gets at how intuition isn't always correct. The last sheet is more practice with the correlation coefficient. Hopefully at the end of this, they will have a better understanding of statistics!!
