Percentages: The most useful statistics ever invented

It can take on values between 0 (none of the whole) and 100 (all of the whole). The whole is called the base. The base must ALWAYS be reported whenever a percentage is determined. Example: There are 20 students in a classroom, 12 of whom are males and 8 of whom are females. The percentage of males is 12 “out of” 20, or 60%. ................
