Conclusiones
El analisis realizado a este conjunto de datos nos permitio
identificar relaciones relevantes entre las variables, la correlacion de
pearson entre tenure y monthlycharges muestra una relacion positiva pero
con un valor pequeño, lo que significa que el monthlycharge depende un
poco del tenure, el diagrama de cajas nos permite ver que los clientes
con contratos mensuales tienden a pagar valores mas altos y hay datos
mas variables, el diagrama de barras permite evidenciar que los metodos
de pago varian segun el tipo de contrato, entre mas largo el contrato es
mas posible que se realice de forma automatica
