Know the key differences between correlation and causation The key differences between correlation and causation Two robust solutions your team can use to test for causation What’s the difference between correlation and causation? While causation and correlation can exist at the same time, correlation...
Correlation is when two variables appear to change in sync. For example, one might decrease as the other increases or vice versa. Causation means one variable directly influences another—for instance, one variable increases because the other decreases. In statistics, correlation expresses the degree...
Correlation only indicates that two variables move together, but it doesn’t tell us if one causes changes in the other. Relying solely on correlation can lead to misguided conclusions and ineffective or even harmful actions. Establishing causality ensures that we’re targeting the root cause of a...
Correlation: An association between two pieces of data. Causation: The act of causing something; one event directly contributes to the existence of another. Randomized Control Trial (RCT): an experimental method used to determine cause-and-effect relationships, where results from a control condition...

Correlation means there is a statistical association between variables. Causation means that a change in one variable causes a change in another variable. In research, you might have come across the phrase “correlation doesn’t imply causation.” Correlation and causation are two related ideas, ...
Genome-wide association studies (GWAS) have emerged as a rich source of genetic clues into disease biology, and they have revealed strong genetic correlations among many diseases and traits. Some of these genetic correlations may reflect causal relationships. We developed a method to quantify causal...

Thanks for this excellent post. I have a question concerning multicollinearity, which you say is a major concern in causal analysis. Specifically, you note that since the goal is accurate coefficient estimates, high correlation between two variables can be devastating because low precision on the co...
