Illustration of Range and Interquartile Range: Two numbers that describe spread: the range covers all the data, and the interquartile range covers only the middle half.
Range and Interquartile Range

ES Rango y rango intercuartílico

Two numbers that describe spread: the range covers all the data, and the interquartile range covers only the middle half.

Dos números que describen la dispersión: el rango cubre todos los datos y el rango intercuartílico solo la mitad central.

Illustration of Range: The distance from the least value to the greatest value, found by subtracting: greatest − least.
Range

ES Rango

The distance from the least value to the greatest value, found by subtracting: greatest − least.

La distancia del valor menor al mayor, que se halla restando: mayor − menor.

Illustration of Quartile: One of the three values that cut an ordered data set into four equal-sized groups.
Quartile

ES Cuartil

One of the three values that cut an ordered data set into four equal-sized groups.

Uno de los tres valores que dividen un conjunto ordenado de datos en cuatro grupos del mismo tamaño.

Illustration of Interquartile range: The distance across the middle half of the data, found by subtracting the first quartile from the third: Q3 − Q1.
Interquartile range

ES Rango intercuartílico

The distance across the middle half of the data, found by subtracting the first quartile from the third: Q3 − Q1.

La distancia a lo largo de la mitad central de los datos: se resta el primer cuartil del tercero: Q3 − Q1.

Illustration of Variability: How much the values in a data set differ from one another — whether they sit close together or far apart.
Variability

ES Variabilidad

How much the values in a data set differ from one another — whether they sit close together or far apart.

Cuánto se diferencian entre sí los valores de un conjunto de datos: si están juntos o muy separados.

Illustration of Measure of variation: A single number that describes the spread of a whole data set. The range and the IQR are both measures of variation.
Measure of variation

ES Medida de variación

A single number that describes the spread of a whole data set. The range and the IQR are both measures of variation.

Un solo número que describe la dispersión de todo un conjunto de datos. El rango y el RIC son medidas de variación.

Illustration of Extreme value: The least or greatest value in a data set, far from the rest.
Extreme value

ES Valor extremo

The least or greatest value in a data set, far from the rest.

El valor menor o mayor de un conjunto de datos, lejos del resto.
