Final answer:
Surveys can yield a variety of statistics on topics such as technology use, music preferences, health issues, education success rates, and public opinion. The data gathered from surveys is instrumental for research, public policy, and understanding societal trends.
Step-by-step explanation:
According to a survey, different statistics are reported based on varying topics such as technology usage, music preferences, disease prevalence, final exam outcomes, societal effects of social media, and public opinion on significant issues. For instance, a Pew Research Center study revealed that 25 percent of Hispanic Americans and 17 percent of Black Americans rely on smartphones for online access versus 12 percent of White Americans. Additionally, a survey about music preferences indicated that out of 571 participants, 80 download music weekly.
Furthermore, survey discrepancies may occur, as illustrated when researchers doubted a newspaper's claim that 13 percent of Americans were diagnosed with a common contagious disease within a year; their own survey with 76 participants found only two diagnoses. Lastly, a California Field Poll found that 79 percent of adults consider education and schools to be a top issue, which is information often used to construct confidence intervals in statistics.
