Solution

Para determinar si un diagrama de puntos o un histograma es más adecuado para representar los datos, es importante considerar cómo se presentan los puntajes.

  1. Los puntajes están agrupados en rangos: 20-29, 30-39, 40-49, 50-59, 60-69.
  2. El número de estudiantes en cada rango es: 4, 7, 5, 4, 3 respectivamente.

Dado que los puntajes no se presentan individualmente, sino en intervalos, un histograma sería más adecuado. Un histograma es útil para mostrar la distribución de datos que están agrupados en rangos o intervalos, lo que permite visualizar la frecuencia de los puntajes en cada rango.

Por lo tanto, la respuesta correcta es:

Histogram, porque un gran número de puntajes se reportan como rangos.
