Pedro y su madre están preparando un pastel para 4 personas cuya receta incluye 150g de harina. Sin embargo, su báscula de cocina no mide a la perfección y utilizan 130g. Dado el éxito de la receta, la semana siguiente repiten la receta en casa de su abuela para toda su familia. Lógicamente esta vez el pastel ha de ser mucho mayor, y la báscula de cocina de su abuela tampoco funciona a la perfección, por lo que de los 600g necesarios utilizan 580g. Razona en este contexto el significado de error absoluto y error relativo y en qué caso se han desviado más respecto a la receta original.
