A researcher wants the smallest margin of error for an estimate of student opinion, using the same survey method and cost per response. Which design is most likely to help?
A
Remove the control group from the survey (using the sample, assignment, and measurement information).
B
Ask only students who already agree with the researcher (based on the design and uncertainty stated).
C
Use a smaller random sample so each response matters more (as the strongest supported conclusion).
D
Increase the number of randomly selected students who respond to the survey (for this evidence).
