Review the blog: Cell-Phones Only---Whom Should Polls Call and answer the following questions: How might an organization like Pew Research obtain an accurate estimate of the number of cell-phone only households in the first place

Answer 1

Pew Research can get an accurate estimate by calling both cell phones and landlines. This is to also include some sample of the population that can be reached only through landlines.

Step-by-step explanation:

When surveying a population for a particular factor or trait, a sample that is representative of the true population must be used. If Pew Research wants to get a correct estimate of the number of households using only cell phones, they need to also recognize the sample of the population that use landlines.

A small percentage of households still use landlines and these should be accounted for in any research or survey. Therefore, landlines should be used to reach households that use only landlines.
