Variable Relationships: Correlation and Causation
Quality during Design
Relationships matter! And they can be difficult to understand.
We're taking relationships between variables. Does one variable affect another? Or do they just correlate? Understanding which matters to the values of our decisions.
We talk about the saying "Correlation does not imply causation", how to find a confounding variable, and ways to check that we've got the triggering cause that's going to affect our outcome.
When we're under pressure to figure something out, it's helpful to stop and remember some fundamentals.
