QUÉ SIGNIFICA VARIANCE EN INGLÉS
Diferencia
En la teoría de la probabilidad y las estadísticas, la varianza mide hasta qué punto se extiende un conjunto de números. Una variación de cero indica que todos los valores son idénticos. La varianza es siempre no negativa: una pequeña varianza indica que los datos tienden a estar muy cerca de la media y, por lo tanto, entre sí, mientras que una alta varianza indica que los datos están muy dispersos alrededor de la media y entre sí. Una medida equivalente es la raíz cuadrada de la varianza, llamada desviación estándar. La desviación estándar tiene la misma dimensión que los datos, y por lo tanto es comparable con las desviaciones de la media. La varianza es uno de varios descriptores de una distribución de probabilidad. En particular, la varianza es uno de los momentos de una distribución. En este contexto, forma parte de un enfoque sistemático para distinguir entre las distribuciones de probabilidad. Aunque se han desarrollado otros enfoques de este tipo, los basados en momentos son ventajosos en términos de simplicidad matemática y computacional.
definición de variance en el diccionario inglés
La primera definición de varianza en el diccionario es el acto de variar o la calidad, el estado o el grado de divergencia; discrepancia. Otra definición de varianza es una instancia de divergencia; disensión. La varianza es también una medida de la dispersión obtenida al tomar la media de las desviaciones al cuadrado de los valores observados de su media en una distribución de frecuencias.
