What is the average amount of time a pa teenager spends per day at the beach1

What is the average amount of time a PA teenager spends per day at the beach?

  • We are 95% confident that the interval for the population mean of hours spent on the beach per day is between 4.808 and 5.82057 hours.

  • In recurring samples of the same size (n=70), the true average of hours spent on the beach per day will catch the interval 95% of the time.


Overall conclusions

Overall Conclusions

  • Overall, PA teenagers favor Ocean City and Wildwood over the other Jersey Shore Points

    • When asking common activities, boardwalk was often chosen

  • Pizza was the most liked “shore food” among PA teenagers

  • The distribution of visited shore points, shore foods, and activities at the shore are not uniformly distributed among PA teenagers


Application to population

Application to Population

  • The population at large could use our information

    • Hot spots for vacationers

    • Most common things to eat on vacation

    • Fun activities to do when at the shore


Possible bias error

Possible Bias & Error

  • Response Bias

    • Online survey

      • Respondents may have fabricated their answers because other people could read them

  • Voluntary Response

    • Drexel Class of 2015 Facebook Group

      • Asked for responses from Pennsylvanian Teenagers

      • Respondents had the option whether they wanted to answer

  • Undercoverage

    • We had 212 responses, but we only took every three so we had 70 subjects

      • Decent population, but there may not be a lot of variability
