Take a little bite out of the statistical concept of correlation in this episode of Stat Snacks. JMP’s Ruth Hummel gives us an overview of what correlation is… and what it isn’t. Is – a measure from -1 to 1 to see how linearly-related variables are to each other. But, two variables can be related to each other without having a high linear correlation. And, correlation doesn’t tell us anything about causality. You get the idea. Correlation is one of many topics covered in JMP’s free online statistics course, Statistical Thinking for Industrial Problem Solving.
