Proyecto1

Descripción de la actividad:

A partir de la información revisada hasta ahora y echando mano de la base de datos anexa, deberás obtener las medidas estadísticas para realizar las solicitudes que se enlistan a continuación; considera que la información obtenida en esta actividad te servirá como base para el desarrollo del proyecto final de la materia, en el que crearás un blog personal de estadística

La base de datos se conformó con la información suministrada por la entidad financiera Bank América. Con base en la tabla, realiza lo siguiente:

 

 

 

 

 

 

 

 

 

 

a) Clasifica cada variable en cualitativa o cuantitativa (discreta o continua)

Sexo: Cualitativo binario

Tipo de contrato: Cualitativa nominal

Salario: Cuantitativa continua

Experiencia laboral: Cuantitativa discreta

Meses desde el contrato: Cuantitativa discreta


b) Elabora una distribución de frecuencias absolutas y relativas para los datos agrupados de la variable salario anual y represéntalas con las gráficas correspondientes





c) Determina la media aritmética, la moda y la mediana para los datos agrupados de la variable salario anual, selecciona una de ellas para que represente al conjunto y explícalas 

El conjunto que lo representa es la mediana ya que no se ve afectada por valores extremos, además se pueden ver salarios tanto bajos como altos      


d) Escribe una conclusión sobre la distribución de los datos

En conclusión, a la representación de las medidas, considero que depende de la distribución de los datos. Algunos datos están sesgados, ya que hay unos pocos salarios muy altos que están alejados de la mayoría de los salarios, entonces tenemos que la mediana podría ser una mejor representación de los datos, ya que no se ve afectada por valores extremos. Por otro lado, la moda puede ser útil para identificar el salario más común, pero en este caso solo se repite en dos ocasiones. En este caso, tenemos que la media y la mediana son bastante cercanas, parece que los datos podrían estar distribuidos de manera bastante uniforme.

g) Realiza un diagrama de tallo y hojas de la variable experiencia laboral y al respecto escribe una conclusión

En conclusión, la mayoría de las personas tienen entre 100 y 200 meses de experiencia laboral, hay menos personas con menos de 100 meses o más de 200 meses de experiencia laboral, ya que estas barras son más bajas en el diagrama. Considero que sugiere que, la mayoría de las personas tienen una cantidad moderada de experiencia laboral, mientras que menos personas tienen niveles muy bajos o muy altos de experiencia laboral.
