Correlation is just a way of describing how two things change together. If one tends to go up when the other goes up, they’re positively related; if one goes up while the other goes down, they’re negatively related; and if there’s no clear pattern, then there’s no real relationship. The important catch is that even when two things seem connected, it doesn’t mean one is causing the other (hello, nondeterminism). -- Made with Umbra Beta #math #statistics #datavisualization #stem #learning
