Understanding the Concept of Average
The term "average" embodies multiple interpretations. Broadly, it signifies a singular number symbolizing a group of numbers. Within mathematics, when we discuss "average", we're typically referring to the arithmetic mean, a foundational statistical concept utilized extensively.
The Mathematical Equation
One of the prevalent definitions of average is represented by the following formula:
Average = Sum ÷ Count
Here, 'Sum' denotes the total after adding all the presented numbers, and 'Count' signifies the total number of values being added.
To elucidate, consider these 5 numbers: 2, 7, 19, 24, and 25. Here's how the average is determined:
Average = (2 + 7 + 19 + 24 + 25) ÷ 5
= 77 ÷ 5
