18\nselect the correct answer.\nthe designers of a standardized test are interested in knowing how long people take, on average, to complete the writing portion of the test. they decide to conduct an observation study at a testing facility. to avoid bias in their study, they create a list of the test takers scheduled to take the test this week. then, they randomly select 50 test takers from the list to be part of the study.\nin this situation, what does the list of test takers represent?\na. a sample\nb. a control group\nc. the population\nd. the frame\nreset next
Answer
# Brief Explanations:
In sampling, the frame is the list from which a sample is drawn. Here, the list of test - takers is what the 50 test - takers are randomly selected from. A sample is the subset (the 50 test - takers), a control group is not relevant in this context as it's not an experimental study with a control and treatment group, and the population would be all possible test - takers, not just those scheduled this week.
# Answer:
D. the frame
