Suppose an SAT preparation course makes the following statement in their advertising brochure: “We asked our graduates to report on their SAT scores before and after taking our course. The mean increase in SAT scores for the 500 graduates who responded was 210 points.” The mean increase of 210 points is likely just a guess for all graduates of the course. The mean increase of 210 points is likely less than the actual mean increase for all graduates of the course. The mean increase of 210 points is likely the actual mean increase for all graduates of the course. The mean increase of 210 points is likely greater than the actual mean increase for all graduates of the course.
