Question 328519
<pre><b>

Add them up:

8+7+7+5+3+2+2 = 34

Now count how many numbers there are:

I count 7 numbers  

1. 8
2. 7
3. 7
4. 5
5. 3
6. 2
7. 2

Now divide 34 by 7

I get 4.857142857 or {{{4&6/7}}}

That's the arithmetic mean.  It's the same thing as
the ordinary average.  That's not listed, so the problem
is botched.
