Answer
Explanation:
Step1: Ordenar los datos
6, 6, 9, 9, 10, 11, 12, 14, 15, 18
Step2: Calcular la mediana
Como hay 10 datos (un número par), la mediana es el promedio de los dos valores del medio. Los valores del medio son el 5º y 6º datos. Entonces, mediana = $\frac{10 + 11}{2}=\frac{21}{2}=10.5$.
Step3: Calcular la media
Sumar todos los datos: $6+6 + 9+9+10+11+12+14+15+18 = 100$. La media es $\frac{100}{10}=10$.
