Question
Using the following data, calculate the mean absolute deviation:7 2 8 5 9 9 5 6 8 1What is the mean absolute deviation for these data? (4 points)2.266.58
Solution
Para calcular la desviación media absoluta (DMA) de los datos proporcionados, sigue estos pasos:
- Encuentra la media (promedio) de los datos.
- Calcula la desviación absoluta de cada dato respecto a la media.
- Encuentra la media de las desviaciones absolutas.
Paso 1: Encuentra la media
Primero, sumamos todos los valores y luego dividimos por la cantidad de datos.
Datos: 7, 2, 8, 5, 9, 9, 5, 6, 8, 1
Suma de los datos:
Cantidad de datos: 10
Media:
Paso 2: Calcula la desviación absoluta de cada dato respecto a la media
Desviación absoluta de cada dato:
Paso 3: Encuentra la media de las desviaciones absolutas
Suma de las desviaciones absolutas:
Media de las desviaciones absolutas:
Por lo tanto, la desviación media absoluta (DMA) para estos datos es 2.2.
