¡Hola lectores!

¡Hola lectores!

En el mundo de la estadística, una parte fundamental es el estudio de las medidas de tendencia central, que son herramientas estadísticas que nos permiten resumir y describir un conjunto de datos de manera concisa y significativa.

Dentro de las medidas de tendencia central más utilizadas se encuentran la media aritmética, la mediana y la moda.

La media aritmética es el promedio de un conjunto de datos y se calcula sumando todos los valores y dividiéndolos entre el número total de observaciones. Es importante tener en cuenta que la media es sensible a los valores extremos, ya que estos pueden distorsionar su valor.

Por otro lado, la mediana es el valor que se encuentra en el centro de un conjunto de datos una vez que estos han sido ordenados de menor a mayor. La mediana es una medida robusta en presencia de valores extremos, ya que no se ve afectada por ellos.

Finalmente, la moda se refiere al valor que más se repite en un conjunto de datos. Puede haber una moda (datos unimodales) o más de una moda (datos bimodales o multimodales).

Estas medidas de tendencia central nos ayudan a comprender la distribución de los datos y a identificar valores representativos dentro de un conjunto de observaciones.

Espero que esta información les haya sido de utilidad. ¡Hasta la próxima!
