# Average with sum of values equal to number of values [closed]

I have a list of numbers. Each number can be any amount above 0 but under 1 million. There are 1 million numbers.

The numbers add up to 1 million.

Is it possible to calculate an average (Mean)? Normally calculating the mean does not work as 1 million / 1 million = 1 of course.

This is a bit of a random question but thanks.

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.

Let us call your numbers $(X_i)_{1\leq i \leq 10^6}$. The mean is defined as $$\mu = \frac{1}{10^6} \sum_{i=1}^{10^6} X_i=1$$ so the mean is $1$. You can either define it as the mean of this specific series or the probabilistic mean in both cases it will be $1$.
• The only case where it could be different from $1$ is if the $X_i$ are correlated to have a sum equal to $10^6$ but that taken alone they have a different distribution. But in that case you need to specify what variables you are talking about. – Jonathan D Feb 15 '18 at 23:21
