You want to know the average gain in reading speed that is made by students who take a speed-reading course. A reading test was given to 250 students before and after they took the course. In looking over the scores, you notice that most students gained 100 to 300 words per minute. However, there are about 20 students who made outstanding gains, ranging from 600 to 1,000 words per minute. Would the mean or the median be a more accurate measure of central tendency, and why?
