Applying subsequent Pearson test for comparing correlation coefficients, we found that the difference between correlation coefficients was significant: participants' RT was significantly more correlated to the amount of difference between sample and test sets (p<0.01).
It's equally important that officials communicate the difference between correlation and cause.
"There is a difference between correlation and explanation," Dr. Chalmers said.
With epidemiological studies, like those at Columbia, in which scientists observe people as they live, without a control group, the real-life nature of the project can make it difficult to distinguish between correlation and causation.

For instance, an induction programme for all new members of the House of Lords would demonstrate to them how the scientific method can inform policymaking, the difference between correlation and causation, and where to go for scientific advice when they need it.
Nor is the public sophisticated in its understanding of the difference between correlation and causation, between direct causation and systemic causation, or even the basic statistical principle of regression towards the mean.
They need a distinction between correlation and causation.
The deviation between correlation calculations and simulation results is less than ±30%.
Figure 5 Relation between correlation of the frequency trajectories and partial ratio.
Indeed, the predictive perspective is based on the confusion between correlation and causation.
