Question

Quizplus · Accepted Answer

Online polls conducted on social networking sites are not random because only those who come across the poll have a chance to participate. This means that the results may not be representative of the entire population being polled. Additionally, there is no way to control who participates in these polls, which can lead to biased results. Finally, there is a risk of response bias, since people who feel strongly about the topic being polled may be more likely to participate. Overall, online polls conducted on social networking sites lack the scientific rigor necessary to be considered reliable sources of data.
