Mesure d’[[corrélation|association]], symbolisée par la lettre &amp;#039;&amp;#039;V&amp;#039;&amp;#039;, de deux variables [[qualitatif|qualitatives]]. Le coefficient &amp;#039;&amp;#039;V&amp;#039;&amp;#039; est une extension du [[coefficient de corrélation phi]] aux cas de croisement de deux variables qualitatives comportant plus de deux modalités.&lt;br /&gt;
&lt;br /&gt;
Dans le cas du croisement de deux variables dichotomiques, le &amp;#039;&amp;#039;V&amp;#039;&amp;#039; de Cramér est égal à la valeur absolue du [[coefficient de corrélation phi|coefficient phi]]&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;V&amp;#039;&amp;#039; est lié à la statistique au coefficient phi et à la statistique [[khi carré]] selon la formule suivante :&lt;br /&gt;
&lt;br /&gt;
