Quiz rápido sobre el CV

by Miranda Antonio
1

Para distribuciones con media cercana a cero, el CV puede ser engañoso o no informativo.

2

Si la media es negativa, el CV es siempre negativo.

3

Un CV alto indica mayor variabilidad relativa respecto a la media.

4

Si todos los datos se multiplican por una constanta, el CV cambia.

5

CV = (σ/μ) × 100%.

6

El coeficiente de variación se calcula como la varianza dividida entre la media.

7

El coeficiente de variación (CV) se calcula dividiendo la desviación típica entre la media y se expresa en porcentaje.

8

El CV siempre es menor que 1 (100%) en cualquier conjunto de datos.

9

El CV es adimensional, sin unidades.

10

El CV se expresa en unidades de la variable original.
