Problem

  1. No. The entire young adult population does not attend college. The comparable data to young adults in the working population may be different than college students.


    One point would be generalizability. College students may have different demographics than the general young adult population. College students may be from more affluent families with greater disposable income. This may lead to a greater frequency of binge drinking. Answers may point out the difference between college students and other young adult populations (military recruits, high school dropouts, etc).


    Another point may include the validity of self-reporting. Problem drinkers may answer intentionally underreport the amount and frequency of alcohol use.


  2. Cross-sectional


  3. 52.4 - 47.2 = 5.2
    5.2 / 52.4 = 9.9%
    Answer = 10%


    64.7 - 48.2 = 16.5
    16.5 / 64.7 = 25.5%
    Answer = 26%


  4. These data indicate an overall decrease in risky drinking behaviors among college students. There has not been a large increase in college students abstaining from alcohol but the drinking student population has moderated their drinking habits, not as many students binge drinking or drinking to get drunk. Overall, the binge-drinking rate among UNL students is higher than college students nationally.
