What is a good definitions for mean(math)?

Answer 1

A mean is some type of averaging. There are LOTS of different means!!!

3 most common means:

1) arithmetic mean
2) geometric mean
3) harmonic mean


Each mean has its own formula and uses. But, the word "mean" conveys a blending and averaging of some sort applied to a group of values.

Answer 2

Mean - the average of all of the numbers within a given set of data.

# In statistics, mean has two related meanings:* the average in ordinary English, which is more correctly called the arithmetic mean, to distinguish it from geometric mean or harmonic mean. The average is also called sample mean.* the expected value of a random variable, which is also called the population mean.

# The mean is the most common measure of central tendency and the one that can be mathematically manipulated. It is defined as the average of a distribution is equal to the SX / N. Simply, the mean is computed by summing all the scores in the distribution (SX) and dividing that sum by the total number of scores (N). The mean is the balance point in a distribution such that if you subtract each value in the distribution from the mean and sum all of these deviation scores, the result will be zero.

Answer 5

the average.take all the numbers, add them up and then divide that sum by however many numbers that you added up
