Biased is like the resuls are not representative of the whole, you asked a group strongly for a certain think

like if you wanted to see how many people want to keep the gym, a biased example would be if you went to the gym becasuse they are all exercising and like exercising, therefor want the gym to stay

biased normally means the person who is doing the survey picks specific people that they know will vote for them

A. not random, these people are picked (she could pick 5 of her friends)

B. random so not biased, but more spread than A

C. also random

A is llikely biased
