Problem |
Near the end of a US cable news show, the host invited viewers to respond to a poll on the show’s website that asked, “Do you support the new federal policy discussed during the show?” At the end of the show, the host reported that 28% responded (“Yes,”) and 70% responded (“No.”) Which of the following best explains why the results are unlikely to represent the sentiments of the population of the United States? |
|
2 |
Step |
Random samples are crucial in polls to ensure that everyone in the population has a fair chance of being included. This helps to get a more accurate picture of what the whole population thinks. |
|
3 |
Step |
People who watch cable news and choose to respond to online polls are a self-selected group. They might have stronger opinions (either for or against the policy) compared to the general population. |
|
4 |
Solution |
So that’s why, Option 2 is correct (Those who responded to the poll were not a random sample of the population of the United States). |

6 |
Choice-A |
Percentages not adding up to 100% wouldn’t necessarily invalidate the poll, it could just mean a small number of people picked "other" or there were rounding errors |
Wrong The percentages do not add up to 100%, so any possible conclusions from the poll are invalid. |
7 |
Choice-B |
This option correctly identifies the potential problem with the sample selection. If respondents to the poll are not a random sample of the population, the results may not accurately reflect the broader sentiment. This is a common pitfall in polling where self-selection bias can significantly skew results |
Correct Those who responded to the poll were not a random sample of the population of the United States. |
8 |
Choice-C |
A \$(50)/(50)\$ split doesn’t necessarily indicate a representative sample either |
Wrong There were not 50% “Yes” responses and 50% “No” responses. |
9 |
Choice-D |
The time to respond might influence the number of participants but not necessarily the representativeness of the sample itself |
Wrong The show did not allow viewers enough time to respond to the poll. |
