Mean: Trung bình

/mēn/

Tiếng Việt: Trung bình

English: The mean is the average of the numbers: a calculated “central” value of a set of numbers. 
To calculate: Just add up all the numbers, then divide by how many numbers there are.

Ví dụ: Trung bình của 4, 3, 8 là (4 + 3 + 8)/3 = 5.

Example: what is the mean of 4, 3 and 8? Add the numbers: 4 + 3 + 8 = 15
Divide by how many numbers (i.e. we added 3 numbers): 15 ÷ 3 = 5
So the Mean is 5.
