The first is the simplest and is called the range. The range is the difference between the maximum value and the minimum value of the data set. A more sophisticated measure of variation is called standard deviation. The standard deviation is a measure of variation based on measuring the distance each data value deviates, or is different, from the mean.

El primero es el más simple y se llama el rango. El rango es la diferencia entre el valor máximo y el valor mínimo del conjunto de datos. Una medida más sofisticada de variación se llama desviación estándar. La desviación estándar es una medida de variación basada en medir la distancia que cada valor de datos se desvía, o es diferente, de la media.
