Complete the following questions.
Scenario: | wish to gather a sample of students at FAU in order to conduct a brief (ten minute) survey. | seek to gather data concerning dating behaviors and relationship attitudes among college students. | go to the breezeway and set up a table where students may opt to come by and complete the survey. In exchange for participating, students receive a $2 off coupon at Barnes & Noble. | set up the same table each day for a week
so that students can also tell their friends to come by and complete this survey, thus maximizing the number of participants in my study. | ultimately collect data from 85 students whose mean age is 21 (standard distribution = 2.5)
What is my population? What is my sampling frame?
What type of sampling is did | use?
What might be some problems with this sampling method?
Does my sampling method have external validity? Why or why not?
How could | improve external validity in this study?
Is the mean age of my population a statistic or a parameter?
Since the standard deviation (SD) of this group is 2.5, then that means 68% of my participants fell between what two ages?
