Question
a poll is being taken on wednesday to predict which movie will be the most popular at the citys movie theaters the next weekend: an animated movie, an action movie, or a romantic comedy. which group would best represent a sample population?
○ every fifth person coming out of the high school.
○ every fifth person in the malls food court at lunchtime.
○ every fifth person coming out of the downtown grocery store at different times throughout the day.
○ every fifth person walking down the street in several different locations throughout town at different times of day.
Para una encuesta para predecir la película más popular, se necesita una muestra representativa de la población general de la ciudad. La opción de las personas caminando por diferentes ubicaciones y horas es la más diversa y menos sesgada. Las otras opciones (salida de la escuela secundaria, food court del centro comercial durante el almuerzo, salida del supermercado) representan sub - grupos específicos y pueden ser sesgados en términos de edad, horario y preferencias, lo que no hace que sean representativos de la población que asiste a cines de la ciudad.
