Definition: The arithmetic mean.

Alright class, settle down and let’s take a look, At a word that pops up, a concept to cook! “Average” it is, a term we all know, But what does it truly mean, let's make it flow. The dictionary tells us, “Arithmetic Mean,” A mathematical measure, a logical scene. It’s not just a guess, or a simple appeal, It’s calculated carefully, for you and for me feel! Think of it this way – let’s say we have some scores, Like tests or baseball hits, from all our learners' cores. We add them together, each number so bright, Then divide by the count, to make everything right! For example, if you scored a 7, then a 9 too, And another 6, it’s simple and true. Add those numbers up – 7 plus 9 plus 6 - that's seventeen, Then divide by three, what do you see? It’s seven! That seven is the average, a middle ground we find, A value that represents the group, of every kind. So remember this lesson, don't be misled, "Average" means the sum divided – it’s perfectly said! Do you have any questions? Let's discuss with glee, Understanding averages is key for you and me!
