There are an infinite number of sets with mean 80. Here are some:
{80, 80, 80}, {80, 80, 80, 80, 80, 80}
{79, 80, 81}, {79, 79, 80, 81, 81}, {79, 79, 80, 82}
(1, 80, 159}, {-40, 200}
To produce a set of n numbers with mean 80,
start with any set of n-1 numbers. Suppose their sum is S. Then add the number 80*n-S to the set. You will now have n numbers whose sum is S+80*n-S = 80*n
So the mean of this set is 80.

What group 0 3 6 27 80 part of?
I am assuming the you do not mean "group", which has a very specific mathematical meaning, but "set". The numbers belong to any set that will contain them! For example, {0, 3, 6, 27, 80}; {0, 3, pi, 6, sqrt(105), 27, 80}; N, the set of natural numbers, Z, the set of integers, Q, the set of rational numbers, R, the set of real numbers, C, the set of complex numbers, the set of integers between -30 and +130, the set of rational numbers between -97/4 and 641/5, the set of positive square roots of all non-negative numbers less than 9000.
Mean of a set of number?
Mean is the same as average. To get the mean of a set of numbers: First, you add up all the numbers. Second, you divide by the number of numbers in the set. Total of all the numbers/Number of numbers in the set
What is the mean a set of numbers?
The sum of the set of numbers divided by the amount of numbers.
What does it mean when you line up a set of numbers from the smallest to largest then divide by 2 if you have an even set of numbers?
You are finding the mean of the set of numbers.
When you add numbers in a set count the numbers in a set and then divide the sum by the count?
You get the mean average of the numbers in the set.
