Answer in a comment on here for the following question:
Explain the difference between a census and a sample. When is a sample biased?
Mariam W A census is a survey that collects data from every member of the population while a sample collects data from some of the population. A sample can sometimes be biased when the amount of people that is surveyed is lets say, more boys than girls. Like we said in class, since the number of boys overpower the number of girls, and since boys usually enjoy FPS games more than girls do, we could have a biased response.
