Is an average of a set of numbers the same as the average of the averages of the subsets of numbers?

No, it is not. Example: the average of (5 and 7) is 6, and the average of (50, 60 and 70) is 60, but if we add all five numbers we have 192, so the overall average is 192 divided by 5 = 38.4
and the reason for that is we have more and bigger numbers in the second set.

How do you calculate an average with fractions?
The same way you calculate averages with whole numbers: Add up all the fractions and divide by the number of fractions there are.
How can you represent how to set of whole numbers integers and rational numbers are related to each other?
Concentric circles. The set of whole numbers is a subset of the set of integers and both of them are subsets of the set of rational numbers.
Are natural numbers subsets of positive integers?
No. Natural numbers are the same set or a superset. The answer depends on whether 0 is excluded or included in natural numbers.
Can you average an average?
You can get the average of an average, but you would be averaging one number, so you would get the same result. You can get the average of a set of averages, though to make sense they will often need to be a weighted average of averages.
What is subset of real number?
There are lots of subsets; some of the ones that are commonly used are: rational numbers; irrational numbers; positive numbers; negative numbers; non-negative numbers; integers; natural numbers. Remember that a subset simply means a set that is contained in another set. It may even be the same set. So the real numbers are a subset of themselves. The number {3} is a subset of the reals. All the examples above are subsets as well. The set {0,1, 2+i, 2-i} is NOT a subset of the real numbers. The real numbers are a subset of the complex numbers.

How do you calculate averages on turing?
The same way you would do averages in regular math; add them all up and divide by the sum of its parts. Ex. if there's three numbers... average := (n1 + n2 + n3) / 3

Is the average the same thing as the mean?
A Mean is a type of average, but there are other kinds of averages too, Modes and Medians.
How do you solve subsets?
You cannot solve subsets - in the same way that you cannot solve people. There may be questions associated with subsets that you may solve but you have not given any questions.
What are industry averages?
An industry average is the average of all data values in the same industry. The data is used to compare a products profitability and growth.

Why are natural numbers whole numbers and integers all subsets of the set of rational numbers?
Because any natural number or whole number, n, can be expressed as a ratio of the two integers n and 1: in the form n/1. And integers are the same as whole numbers.
If you are a 10 year old boy and your IQ is averages at a 15 year old. What is you IQ?
100. The average is the same regardless of age.
Average of numbers?
To find the average of a given set of numbers, total the numbers and divide that total by the number of members of the set.
