Solution
a. Para construir una tabla de distribución de frecuencias, primero necesitamos contar cuántas veces aparece cada puntuación en el conjunto de datos.
| Puntuación | Frecuencia |
|---|---|
| 4 | 1 |
| 5 | 2 |
| 6 | 3 |
| 7 | 4 |
| 8 | 4 |
| 9 | 4 |
| 10 | 2 |
b. Para dibujar un histograma de distribución de frecuencias, se puede usar la tabla anterior. En el eje horizontal (x) se colocan las puntuaciones y en el eje vertical (y) se colocan las frecuencias. Cada barra del histograma representa la frecuencia de cada puntuación.
