This video tutorial uses a variety of examples to introduce the concept of averages.
The instructor explains that finding the average, or mean, involves taking a total value and dividing it by the number of units represented by that total. For example, if three students score 90, 85 and 80 respectively on a test, the total value of their marks is 255. To find the average mark, it is necessary to divide the total of 255 by three, the number of students, which shows they had an average score of 85.
