Question

hayden, from the blog \hanging with hayden,\ directly sent an email to her readers age 18 to 21 and asked the survey question, \if you had the chance, would you want to be president?\ of the 1,200 readers to whom she sent an email, 567 responded, and 35% of those who responded said no. what does this show? no meaningful conclusion is possible without knowing something more about the characteristics of haydens readers. the survey would have been more meaningful if hayden had picked a random sample of the readers who responded. the survey would have been more meaningful if hayden had used a control group. this was a legitimate sample, drawn randomly from her readers, and is of adequate size to allow the conclusion that most of haydens readers do not want to be the president. the survey is meaningless because of nonresponse bias.

Explanation:

Hayden sent an email - survey to a specific age - group of her readers. Only 567 out of 1200 responded. Non - response bias occurs when those who don't respond may have different opinions than those who do. Without knowing the characteristics of non - respondents, the results are unreliable.

Answer:

The survey is meaningless because of nonresponse bias.
