How can we use 2 variable statistics in real life?
We can use correlation and causation. Because we can use data that we have collected and determine if one variable is causing the other to happen. For instance, the amount of unsupervised children and the amount of car accidents has a good correlation because when children are unsupervised they make bad decisions and it could cause them to get in a car accident.
