Suppose we are hired by a politician to determine the amount of support he has among the electorate. What population should we study? How do we choose an appropriate sample? There are many ways to sample a population, but there is one goal we need to keep in mind: we would like the sample to be representative of the population.

There are many ways to take samples. Not all of them will result in a representative sample. Also, just because a sample is large does not mean it is a good sample.

Supongamos que somos contratados por un político para determinar la cantidad de apoyo que tiene entre el electorado. ¿Qué población debemos estudiar? ¿Cómo elegimos una muestra adecuada? Hay muchas formas de muestrear una población, pero hay un objetivo que debemos tener en cuenta: nos gustaría que la muestra fuera representativa de la población
