In statistics, we try to make sense of the world by collecting, organizing, analyzing, and presenting large amounts of data for example, you may survey your friends about what tv show is most popular, but the small sample size will not give you an accurate idea of what all 6th graders like to watch to do this you must survey a cross section of.
