Adding an Element to a Group Average
When you add an element to a group average, it will change the overall average value. For example, if you have a group of 5 students with the following scores: 5, 7, 8, 9, and 10, the average score is 8. If you add the element 12 to the group, the average score will become 9.
Removing an Element from a Group Average
When you remove an element from a group average, it will also change the overall average value. For example, if you remove the element 12 from the group mentioned above, the average score will become 7.
