Experimental Coding in Designed Experiments

To support the creation of videos like this, and get exclusive content, early access, and a behind-the-scenes look at my channel, support me on patreon: https://www.patreon.com/edmundsj This is part of my series on statistically designed experiments, you can find the full playlist here: https://www.youtube.com/watch?v=0doSd1GIOgY&list=PLQms29D1RqeK8CD07poR3KkicY79s3a2H In this video I discuss experimental coding, where we convert variables which have units (such as temperature in degrees, or volume in liters) to codes, typically +1, -1, and 0. I discuss why we would want to do this, and give an example where you might draw exactly the wrong conclusions if you didn't properly code the experiment.
