Solution

Para responder a la pregunta, sigamos los siguientes pasos:

  1. Identificar el concepto clave: La pregunta se refiere a la "fiabilidad" según la sugerencia de Nunnally (1978).
  2. Entender el contexto: Nunnally es conocido por sus trabajos en psicometría y fiabilidad de pruebas.
  3. Determinar el rango adecuado: Según Nunnally, un rango adecuado para la fiabilidad es generalmente aceptado como .70 a .90, aunque en algunos contextos más rigurosos, se prefiere .80 o más.

Ahora, evaluemos las opciones proporcionadas:

  • -1 to +1: Este rango no es adecuado para la fiabilidad, ya que la fiabilidad se mide en una escala de 0 a 1.
  • .60 to at least .80: Este rango es aceptable en algunos contextos, pero Nunnally sugiere que .70 es un mínimo más adecuado.
  • .70 to at least .90: Este rango es el más adecuado según la sugerencia de Nunnally.
  • 0 to 1: Aunque este rango es técnicamente correcto, no es específico y no refleja la recomendación de Nunnally.

Por lo tanto, la respuesta correcta es: .70 to at least .90.
