This is the concept of statistics, given that there are 650 students and all of them read a total of 18,996 pages. We are required to get the average number of pages that they all read; Average, otherwise known as the mean is the calculated 'central' value of a set of numbers; The formula for mean is given by; mean=(sum)/(count) in our case: sum=18,996 count=650 thus; mean=18996/650 =29.23 Here we can conclude that the average number of pages read by each student in the High School was 29.23
