Question
look at this set of 8 numbers: 73 37 47 13 96 14 59 74 how would the median change if the number 41 replaced the number 73 in the set? increase decrease no change
Step1: Ordenar los números originales
$$13, 14, 37, 47, 59, 73, 74, 96$$
Step2: Calcular la mediana original
Como hay 8 números (par), la mediana es el promedio de los 4º y 5º valores:
$$\frac{47 + 59}{2}=\frac{106}{2} = 53$$
Step3: Reemplazar 73 por 41 y ordenar
$$13, 14, 37, 41, 47, 59, 74, 96$$
Step4: Calcular la nueva mediana
Promedio de los 4º y 5º valores:
$$\frac{41+47}{2}=\frac{88}{2}=44$$
