Answer:
the mean is the average of a set of numbers
Step-by-step explanation:
for example, if a set of numbers were 1,2, and 3, the mean would be 2 because the average is 2.
This can be calculated by adding 1, 2, and 3, and dividing them among all three numbers
1+2+3 = 6
6/3 =2
there are three numbers in the data set that we were trying to get the mean from
give brainliest, please! hope this helps :)
Answer:
generally, the sum divided by the number of summands
Step-by-step explanation:
In math the term "mean" can have different meanings, depending on the context. It will generally refer to the arithmetic mean, if no additional qualifiers are given. The arithmetic mean is also called the average.

arithmetic mean
The arithmetic mean of a set of numbers is their sum, divided by the number of numbers. It is sometimes represented by the Greek letter μ or a variable with an overbar.
[tex]\overline{x}=\dfrac{x_1+x_2+\dots +x_n}{n}[/tex]
geometric mean
The geometric mean will be the n-th root of the product of n numbers.
[tex]\text{geometric mean}=\sqrt[n]{x_1\cdot x_2\dots\cdot x_n}[/tex]
harmonic mean
The harmonic mean is the reciprocal of the arithmetic mean of the reciprocals.
[tex]\text{harmonic mean}=\dfrac{n}{\dfrac{1}{x_1}+\dfrac{1}{x_2}+\dots+\dfrac{1}{x_n}}[/tex]
proportion
In a proportion written as ...
a/b = c/d
The two values closest to the middle of the expression (b and c) are called the "means". Those farthest away (a and d) are called the "extremes". It is said that ...
the product of the means is equal to the product of the extremes
