Correlatie symbool
WebDe correlatiecoëfficiënt bepalen. De correlatiecoëfficiënt, aangeduid als r of ρ, is de maat voor de lineaire correlatie (de relatie, zowel qua sterkte als qua richting) tussen twee variabelen. Hij varieert van -1 tot +1, waarbij plus- en mintekens worden gebruikt om de positieve en negatieve correlatie weer te geven. WebBij correlatie van +1 of -1 is er een perfect verband. In dat geval is de waarde van Y volledig te herleiden uit de waarde van X (en omgekeerd). Bij de waarde van 0 is er geen enkele lineaire samenhang. De correlatie waarde is zogenaamd dimensieloos; dit betekent dat de correlatiewaarde ongevoelig is voor de eenheden waarin X en Y gemeten zijn.
