What does mean in a sentence?

Mean is defined as the average of a set of numbers.

Answer: Mean is the ratio of the sum of all given observations to the total number of observations.

The mean is a numeric value which is a single representation of a large amount of data.

Explanation:

Suppose we have a list of numbers containing {1, 2, 3, 4, 5, 6}. Then, its mean is (1 + 2 + 3 + 4 + 5 + 6) / 6 = 21/6

Therefore, the mean is the ratio of the sum of all given observations to the total number of observations.
