Quizplus · Accepted Answer

Karen used a haphazard or convenience sampling technique, as she simply asked the people walking by her condo building. It is not a representative sample of the population and is biased towards the people who happened to pass by at that particular location and time. It is not a reliable or valid method for drawing conclusions about the entire population of Torontonians.
