Which of the following sampling techniques is the most likely to produce a random sample, representative sample of all students
at a high school? A. Choosing every 10th name on the student roster
B. Choosing every 10th student arriving in a 9th grade homeroom
C. Choosing the first 100 students who arrive at school
D. Asking students to call a phone number to answer survey questions
➷ A. choosing every 10th name on the student roster.
This is the most random as it is non biased. The first and second one are biased towards the student who arrive early and therefore, wouldn't produce a random sample. The last one is also not random as it relies on volunteers.
