La prueba de “chi cuadrado” se puede utilizar para determinar:

1. El grado de asociación en variables cuantitativas.
2. Comparación de medias en dos muestras.
3. La igualdad de varianzas en dos grupos.
4. El grado de asociación en variables cualitativas.

Respuesta del ministerio: 4


En mi opinión, el chi cuadrado establece si existe o no una relación entre variables cualitativas, pero no mide el grado de asociación. El grado de asociación se mide con correlaciones, pero no con el chi cuadrado. Consideráis que podría ser impugnada? gracias!
