La medidas de posición y variabilidad que se definen son la media aritmética o media, la desviación estándar y el coeficiente de variación • Media aritmética o media : Es el valor promedio del conjunto de mediciones Xi •Desviación estándar: Es una medida del alejamiento de los datos del valor promedio •Coeficiente de variación: Es la desviación relativa de los datos respecto del valor promedio CV = ds__x_100 X
