Experience 14 - Linear Correlation
Many studies often espouse to have evidence that one variable is causing another. This is often based on the grounds that changes in the two quantities are correlated or related through an approximately linear mathematical relationship. While jumping from correlation to causation is a fallacy of logic we can often learn a lot from correlation and should know when and how it is justified. Given paired data sets we can try to find a pattern and use technology to pinpoint that relationship. From these relationships we can better understand the world around us.
